evagents's Introduction
======================================================================================================================= Evagents Authors & Contributors: Julian Hershey, Andrej Karpathy, Casey Link, David Coleman Supporters: Eric Hvinden, Max Brage License: BSD (see end of file) Project website and attached forum: https://sites.google.com/view/evagentsproject/home ======================================================================================================================= WHAT IS EVAGENTS? Evagents is a "natural" selection simulator written for Windows platforms. The program contains a world wherein simple agents can interact with that world and each other, reproduce, die, run around, eat, breed, communicate, and other things, using neural nets to calculate their responses to stimuli. Each agent has a huge number of features available to them that they can use in various ways to try and survive long enough to reproduce, extending their solution through time. Any time a baby is born its traits are copied from it's parent(s), but with chances of mutations. Thus a form of natural selection is applied to create populations of species that can best survive in the world. Competition and cooperation are important secondary characteristics that agents must develop, using their brains, a neural network with features of Connection-Positive, Dampened, Recurrent, Additive, Weighted, Sigmoid-processed outputs that take sensory inputs (in range 0-1), process them with finite but potentially complex iterations, and produces outputs (also 0-1) over time and in an initially random structure. As time passes, however, the brains can mutate into more efficient forms, via adding/removing connections, changing connection targets and sources, changing weights, biases, and dampening factors, and more. ======================================================================================================================= BUILDING: (for users that want to edit the source code) To compile Evagents you will need: + Microsoft Windows + MS SDK for Windows Server 2008 and .NET Framework 3.5 (https://www.microsoft.com/en-us/download/details.aspx?id=11310) + OpenGL (http://www.opengl.org/resources/libraries/glut/). Note: OpenGL is typically included in Windows distributions, so a manual DL is not usually required. It will use OpenMP to speed up everything, in case you have multi-core CPU, and OpenGL + GLUI to draw a user interface. Take the provided .vcproj file and edit the files as you desire, compile and enjoy! ======================================================================================================================= QUESTIONS, COMMENTS, ISSUES are best posted on Evagents sub-Reddit, available here: - https://www.reddit.com/r/Evagents/ More details can be learned from our Wiki, located here: - https://sites.google.com/view/evagentsproject/wiki ======================================================================================================================= LICENSE CLAUSE: Redistribution and use in source and binary forms are permitted provided that the above Authors list, project name, and this paragraph are duplicated with all distributions, and that any documentation, advertising materials, and other materials related to such distribution and use acknowledge that the software was developed by the Authors.

evagents's Issues
Autosaves are broken in versions 0.04 and 0.04.1
Versions Effected:
0.04.0
0.04.1
Workaround: add the extension ".SAV" to the file named "AUTOSAVE" in the "saves" folder. This will have to be done each time you want to load a new or updated autosaved world.
This issue has been fixed for future versions.
