Thanks for that. My undergrad was Industrial Engineering but I always loved the Operations Research stuff (which I'm hoping will lead me to more CS-y stuff if I can get a job or a Masters or something). All that OR with LPs and MIPs was a headache and but somehow Stochastic programming, GAs and NNs were scary and I never even tried to understand them. I always thought people describing them as simple were probably geniuses or something. Maybe one day I'll understand the second half of that link.
