These examples use genetic algorithms to evolve a combination of five numbers and four operators to create a simple expression that evaluates to a target answer.

For instance, we choose any five numbers between 0 and 9, then we choose four math operators from { +, -, *, / }. The goal is to create an expression that evaluates to a target value like 100. Evaluation goes from left to right. Something like this: 4 + 7 + 6 * 6 - 2 = 100

There are numerous combinations that can evaluate to 100, and these algorithms just need to come up with one.
