Improve it or lose it: evolvability costs of competition for expression

MATLAB simulation code and scripts reproducing all figures in Moran, Finlay, Tikhonov (2020), "Improve it or lose it: evolvability costs of competition for expression" . Optional pre-computed simulation data included to speed-up figure plotting -- remove or rename any data file to rerun the corresponding simulations from scratch.复现莫兰（Moran）、芬利（Finlay）与季洪诺夫（Tikhonov）2020年发表的论文《精进则存，退化则亡：表达竞争的可进化性成本》（Improve it or lose it: evolvability costs of competition for expression）中所有图表的MATLAB仿真代码与配套脚本。附带可选的预计算仿真数据以加快图表绘制速度——若需从头重新运行对应仿真，可删除或重命名任意数据文件。
