I'm enrolled in a course of ML, and we were asked to provide a problem domain for a fitness functions over bit string where we have to find the value of X which maximize the output of the function.
The problem is that I really know nothing about bit string or bit string functions. Perhaps, If I know what are they exactly, I could complete my assignment.
I would appreciate any explanation with an example
A bit string is just a string of bits, of zeros and ones. A bit string function is a function that takes a bit string and produces a result. It might be the number of $1$s in the string, it might be the total length, it might be anything. Fitness functions presumably return a result between $0$ and $1$ and can be thought of as the likelihood of survival of a set of genes. It might be that certain positions reward $1$s and others reward $0$s. There might be correlations, like position $2$ and $5$ should be the same for maximum fitness.
