Incentives for bots?

Question

Lets say for this question, you want to create a bot that can sort a shelf. Lets also assume you are the most fluent person in every programming language ever. How do you compare the bots? For example; you want them to sort the shelf the fastest, Bot A and Bot B compete, and Bot B loses. What do you do to Bot B? Do you personally rewrite his code or is there some sort of code that you can implement that would tell the bot to try again this time faster. If you are confused, see this site for an example of how bots learn to find the fastest route: https://www.openprocessing.org/sketch/205807.

Answer 1

Traditionally, Bot B would be discarded. More Bots would be made to compete with Bot A. Once Bot A has been defeated the bot that defeated it would then repeat the same process.
