Conways game of life command line output1/17/2024 ![]() Here's the easier-to-read version (with unnecessary newlines and whitespace added for better formatting): function l(f,N),Īnd here's how the program is run from the MATLAB Command Window: l('in.txt',100)Īfter a comment about calling functions with a command syntax, I dug a little deeper and found out that MATLAB functions can in fact be invoked with a command-line format (with some restrictions). The winner will be determined by character count. EDIT: You do need to have newlines in your output file.You don't need to deal with the edges of the board (wraparound, infinite grids.You need to generate out.txt (overwrite if it exists) in the specified format.You need to accept an input file and the number of iterations as arguments.You need to use file I/O to read/write the files.Here is an example run with relevant files: Finally, it will output to an ASCII file out.txt the state of the system after N iterations. Your program will read in a 40x80 character ASCII text file specified as a command-line argument, as well as the number of iterations (N) to perform. Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction.Any live cell with two or three live neighbours lives on to the next generation.Any live cell with more than three live neighbours dies, as if by overcrowding.Any live cell with fewer than two live neighbours dies, as if caused by under-population.We determine which cells are alive in the next step of time by applying the following rules: Cells can be alive (filled) or dead (empty). ĮDIT: After about a week of competition, I have selected a victor: pdehaan, for managing to beat the Matlab solution by one character with perl.įor those who haven't heard of Game of Life, you take a grid (ideally infinite) of square cells. Conway's Game of Life cellular automaton. The Challenge: Write the shortest program that implements John H. It is not currently accepting new answers or interactions. This question and its answers are locked because the question is off-topic but has historical significance. If you’re a TypeScript person and would like to change things, please feel free to raise an issue or open a pull request.Locked. You can check it all out on the GitHub page for the repo. Test ( ' when there is a glider on the board, it moves ', () =>, 250 ) I’m going to use jest for the tests, which needs some help to work well with TS. I could start by copying my tests from the JS implementation I wrote years ago, but that would ruin some of the fun and purpose of this exercise. ![]() It’s a very effective tool for teaching basic TDD to junior developers, and I’d recommend it. In fact, my first exposure to Conway’s Game was during an exercise intended to demonstrate how Test-Driven Development (TDD) works. Whenever I build the GOL I insist on writing tests first. ![]() Or, if you want to see my favourite implementation of GoL I’ve done, check out the one I made with React. I’m going to write this devlog as I go, so I may include in it some challenges I’ve faced as they may be interesting to read about and learn from.ĭon’t wanna read this? Just want the code? Here is the GitHub repo. So, starting with the Game of Life is as good as any start with the language. However, I haven’t used it more than once or twice in small ways before. I suspect one day I will have a job where I’ll need to write a lot of TypeScript. It’s quite common these days for JS developers to espouse the benefits of TypeScript. In some cases, it could be a good introduction which leads to more serious use of the language, like a tasting menu of code. And finally, I do it because I’ll never have time to learn all the programming languages, but I may have time to at least expose myself to a little bit of them. I do this because I really like the Game of Life as a concept. I do this because t’s fun to have a collection of repos that do the same thing with different technologies. ![]() So far, I’ve done JavaScript, JavaScript with React, Python and Go. I have an ongoing project on GitHub to build a collection of implementations of Conway’s Game of Life using various technologies.
