How to apply time series data in Genetic Algorithm?

Hello. I want to find the optimal segment for my solar radiation series by Genetic Algorithm.

I have converted the decimal data to binary. There are two constraints. 1- The first and last gene of each chromosome should be 1.2- no two adjacent genes should be 1.

The question is: What would be the initial population here? Time series Data or something? Does it mean that I should load the data then obtain its size, then this size would be number of population and because I have the exact data I don't need to generate the initial population??

I really don't know how to begin!!! Could any one help me?
