GENESIS - the GENEric SImulation System for modelling state transitions.

This software is a highly-configurable way of modelling transitions between states, given known transition probabilities. It could therefore be used to model a disease progression and/or recovery in a population, or maybe an environmental process. A test suite is included.You can have multiple branching and also bi-directional transitions.Full instructions are given in the README.txt file. You will need to have Perl installed, and a C++ 11 compiler. This software has been tested on both Windows and Linux.You need to have a “state transition table” called stt.txt, and an example is provided. You also need a configuration file config.txt, which sets the initial parameters for the program, and again an example is provided.Link to <i>JORS </i>paper.UPDATE May 2026: I am finally working on a Python (to C++) version! Hopefully this will be easier for people to install and use.Link to GenesisPy GitHub repo.<br><br><br>

本软件为一款高度可配置的状态间转换建模工具，支持基于已知转换概率开展建模工作，可用于模拟人群中疾病的进展与转归过程，或各类环境演化进程。软件附带完整测试套件，支持多分支及双向状态转换。详细使用说明详见README.txt文件。运行本软件需预先安装Perl环境及C++11标准编译器，且已在Windows与Linux系统上完成测试验证。用户需提供名为stt.txt的状态转换表（state transition table），软件附带该文件的示例模板；同时需提供配置文件config.txt以设置程序初始参数，该文件同样附带示例模板。可访问<i>JORS</i>相关论文链接。2026年5月更新：目前我正推进Python（转译至C++）版本的开发工作，有望大幅降低软件的安装与使用门槛。可访问GenesisPy GitHub仓库链接。
