I figured out I want to have commands for generate, evaluate, select, and visualize. Working on implementing those, I needed to compare the first argument to the command with a string. Turns out even something as simple as this is … tricky.
I’ll skip to the answer:
if (!strcmp(argv[1], "generate")) generateStuff()
strcmp compares the values that the pointers point to and returns zero if they MATCH.
if (argv[1] == "generate") WRONG
This doesn’t work because it’s comparing the two pointers.
Thanks, C++.

I dunno if my MainGenerate and MainVisualize classes are necessary but it makes my main.cpp smaller and makes me happy so I’ll keep it that way for now, I guess. Got a very very basic generate command working. It produces 10 boids with random weights. Next I’ll try reading it when I load up the visualize command.
…
I should include the generation number for these boids. (How many generations of evaluation and selection and mutation have they been through?)
