Hello,
I have a genetic algorithm that is running an old simulation model many, many times. The problem is that this model, that I inherited, has terrible graphics that do not clean up nicely. I have the model running as a separate process (ext:run-program). This is my shortcut around the poor graphics not cleaning up. The only way that I can get the model to run multiple times is to spawn a new lisp listener that runs the model as a PTY. This was a guess and I don't know why it worked. I can't find any real information about PTYs and I have now realized that there seems to be a limit on how many you can create. Do I have to "kill" them or is there some way to "free" them up to spawn more. Any help would be excellent. Thanks. Kevin Tor Penn State University
