They used a SAT solver, which inspired me to write a blog post about SAT solvers applied to sprint planning. If you guess unnecessarily, you always lose - but if you’re forced to guess then you’re guaranteed to be correct.Īs part of that, they had to use a Minesweeper solver to know when guessing was needed. While researching Minesweeper solvers, I came across Kaboom, a version of Minesweeper which forces you to play methodically. The main complaint was the number of people (and fire sprinklers) I hit with chocolate projectiles! Artifact 5: An article about SAT Solvers People enjoyed it (including the venue staff!) and I think they understood what I was going for. The military-industrial complex, of course! Introduce a theme and the audience participationīut what theme would I pick for a presentation about clearing minefields?.Humorous introduction without theme to set a light-hearted tone.I’d never seen a tech talk with heavy audience participation, so I relied on my experience with Improvised Comedy. With my game complete, I needed to think about how to do the actual talk. You can view the source code on GitHub or try a live version of the game on my website. I called it Minesweeper Constrained, and it served its purpose - though it wasn’t exactly efficient. It forced you to act like an algorithmic solver, manually combining and clearing constraints. I had a week’s notice before the talk, and thankfully had nothing else to do.Īfter spending every available moment working on it, I finished my version of Minesweeper with a few hours to spare. Since this talk was going to be even more in-depth, I decided to include audience participation to keep people engaged.Īdding audience participation just raised the bar - it’s one thing to understand a talk, but it’s another thing entirely to understand well enough to participate! I knew from my previous talk that the audience was getting a bit lost when things got complex. So, I was invited to give a long-form talk, in a 15 minute slot. If you’re not prepared to listen to me shout for 3 minutes, you can just read the slides on my website. One member of the audience enjoyed it so much that I was invited to give a longer version at the local meetup, NE:Tech. It paid off though - I finished perfectly on time, and the audience really enjoyed it. I spent 2 days straight preparing for this 3 minute talk, which I titled How to solve Minesweeper in 3 minutes. It didn’t help that everyone kept telling me that Lightning talks are the hardest kind of tech talk! It was my first real Tech Talk, and I was well outside my comfort zone. I knew exactly what I wanted to talk about, and jumped at the chance to indoctrinate the rest of the office! It was time for Scott Logic’s annual Christmas Lightning talks, and my Minesweeper obsession was in full swing. I thought that writing the solver would satisfy me and end my obsession - but it only made me want to do more… Artifact 2: A Lightning Talk I’m not particularly proud of it, so here’s someone’s dissertation on the topic instead. Looking back, this was inevitable given that Minesweeper is NP-Complete.Īll in all, the solver was good, and my constraint-based technique worked, but it wasn’t a great bit of programming. Making things worse, at one point I sat for 5 minutes assuming it had crashed, only for the solver to then report it had processed 5 million constraints! It never made a mistake, but occasionally it would get stuck in a situation that I could solve manually. I did finish my solver, and it worked - but it wasn’t flawless. If you want the details of how it all works, watch one of the talks later in this post or have a look at the Minesweeper Constrained readme. My solver defined Minesweeper as a set of constraints.Įach constraint declared This set of unknown cells contains between and mines. That meant a lot of downtime, and I just happened to have a laptop with IntelliJ. We were on our honeymoon at the time, travelling around Europe by train. Two months on, I can think of at least six side projects that are the direct result of my Minesweeper obsession. It all snowballed from there - implementing the solver was just the beginning. Most of the time, I don’t actually implement that algorithm. When playing a game, I often think about how I’d write an AI for it. It was a dark time - I even spent £3.99 for a Nintendo Switch version! In this post, I tell the story of my recent obsession with the game Minesweeper and discuss why having an obsession can be helpful.Ī few months ago, my wife and I were playing a lot of Minesweeper.

Dynamic RAM has to be dynamically refreshed all of the time or it forgets what it is holding. This refresh operation is where dynamic RAM gets its name. It needs to be refreshed periodically or it will discharge to 0. The capacitor in a dynamic RAM memory cell is like a leaky bucket. This refresh operation happens automatically thousands of times per second. To do this, the memory controller reads the memory and then writes it right back. Therefore, for dynamic memory to work, either the CPU or the memory controller has to come along and recharge all of the capacitors holding a 1 before they discharge. In a matter of a few milliseconds a full bucket becomes empty. The problem with the capacitor's bucket is that it has a leak. To store a 1 in the memory cell, the bucket is filled with electrons. The transistor acts as a switch that lets the control circuitry on the memory chip read the capacitor or change its state.Ī capacitor is like a small bucket that can store electrons. The capacitor holds the bit of information - a 0 or a 1 (see How Bits and Bytes Work for information on bits). In the most common form of computer memory, dynamic random access memory (DRAM), a transistor and a capacitor are paired to create a memory cell, which represents a single bit of data. Similar to a microprocessor, a memory chip is an integrated circuit (IC) made of millions of transistors and capacitors. RAM is basically your computer's short-term memory. From a standstill, engaging the clutch too slowly will wear out the disc prematurely, and engaging it too quickly will cause the engine to stall.Īn automatic transmission is connected to the engine via a hydraulic torque converter, and a dual-clutch automatic relies on a pair of clutches. Release the clutch, select the desired gear, and engage the clutch again. To change gears, a clutch disc sandwiched between the engine and the transmission needs to be released via a third pedal located on the left side of the brake. The shift lever is commonly mounted vertically on the center console and connected to the transmission via a linkage. The driver literally uses a stick to change gears. However, there are two big differences between them there is no clutch pedal in an automatic transmission car, and there is no gearshift in an automatic transmission car.Ī manual transmission is also known as a stick-shift. Each gear has a specific ratio to ensure the wheels don't spin at the same speed as the engine.Īutomatic and manual transmissions both perform the same basic function, however - they channel the power generated by the engine to the drive wheels. It acts as a mediator between the engine and the wheels, and converts the high power the engine produces into torque (rotational force), which is then transferred to the axles that in turn rotates the wheels. It is a metal case that contains a series of gears, hence the name gearbox. Your transmission is the powertrain that converts the engine's force into a controlled source of power. Maintaining the gearbox is important-and often overlooked. But all too often, car owners misunderstand the basic maintenance that's needed to keep a gearbox running smoothly. Taking care of your car or truck's transmission is important for its long-term health. Our new data demonstrates that reducing the dominant eye's mean luminance reduces its suppression of the non-dominant eye, and therefore rebalances the asymmetric binocular vision. Reanalysing our previous data, we found that, at a given spatial frequency, the binocular asymmetry could be described by a log-linear formula with two parameters, one for the maximum asymmetry and one for the rate at which the binocular system becomes asymmetric as the contrast increases. Amblyopic binocular vision becomes more and more asymmetric the higher the stimulus contrast or spatial frequency. We varied both the relative contrast and luminance of the two eyes' inputs, in order to rebalance the asymmetric binocular vision. We measured the perceived phase of a cyclopean sinewave by asking normal and amblyopic observers to indicate the apparent location (phase) of the dark trough in the horizontal cyclopean sine wave relative to a black horizontal reference line, and used the same stimuli to measure perceived contrast by matching the binocular combined contrast to a standard contrast presented to one eye. The purpose of this study was to develop new models and methods for rebalancing this asymmetric binocular vision by manipulating the contrast and luminance in the two eyes. Humans with amblyopia have an asymmetry in binocular vision: neural signals from the amblyopic eye are suppressed in the cortex by the fellow eye. Rebalancing binocular vision in amblyopia. This provides the basis for a new treatment of amblyopia, one that is purely binocular and aimed at reducing suppression as a first step. We have implemented this approach on a headmounted device as well as on a handheld iPod. Additionally, stereoscopic function was established in the majority of patients tested. Concomitant improvement in monocular acuity of the amblyopic eye occurs with this reduction in suppression and strengthening of binocular fusion. Furthermore we show that prolonged periods of binocular combination leads to a strengthening of binocular vision in strabismic amblyopes and eventual combination of binocular information under natural viewing conditions (stimuli of the same contrast in each eye). We demonstrate that strabismic amblyopes can combine information normally between their eyes under viewing conditions where suppression is reduced by presenting stimuli of different contrast to each eye. We hypothesize that suppression renders a structurally binocular system, functionally monocular. A novel procedure is outlined for measuring and reducing the extent to which the fixing eye suppresses the fellow amblyopic eye in adults with amblyopia. To develop a treatment for amblyopia based on re-establishing binocular vision. Restoration of binocular vision in amblyopia. Adding binocular contrast gain control to the modified Ding-Sperling model enabled us to predict the results of dichoptic and binocular contrast discrimination experiments By introducing asymmetric parameters to the modified Ding-Sperling model including interocular contrast gain enhancement, we succeeded in accounting for both binocular combined phase and contrast simultaneously. We found asymmetric interocular interactions in binocular contrast perception, which was dependent on both contrast and spatial frequency in the same way as in phase perception. These measures provide strong constraints for model fitting. In the second experiment, we used the identical stimuli to measure the perceived contrast of a cyclopean grating by matching the binocular combined contrast to a standard contrast presented to the DE. However, in these abnormal observers the NDE-to-DE suppression was weak or absent. This enhancement is not evident in normal vision because it is normally masked by interocular suppression. Our results also revealed a surprising NDE-to-DE enhancement in some of our abnormal observers. This asymmetry between the two eyes is larger than predicted from the contrast sensitivities or monocular perceived contrast of the two eyes and is dependent on contrast and spatial frequency: more asymmetric with higher contrast and/or spatial frequency. However, in observers with strabismus and/or amblyopia, balanced vision requires a higher contrast image in the nondominant eye (NDE) than the dominant eye (DE). Normal observers have balanced vision between the two eyes when the two eyes' images have equal contrast (i.e., both eyes contribute equally to the perceived image and perceived phase = 0°). In the first experiment we presented the two eyes with equal but opposite phase shifted sine waves and measured the perceived phase of the cyclopean sine wave. We investigated suprathreshold binocular combination in humans with abnormal binocular visual experience early in life. Binocular combination in abnormal binocular vision.ĭing, Jian Klein, Stanley A Levi, Dennis M Every company or management team is now looking for options to keep their consumers happy.
