How to test my flood it solver algorithm by universal standard?

We are developing a flood it game solver by Greedy and A* search for an Ai project, how can we test it our algorithm is optimal and good or not ? we used a code that sets number of moves by taking the minimum of multiple runs, so far our solver works greatly with high wining rate,

but how can we test the algorithm for real ? we didn't use any standards but devolved a simple algorithm using only a set of arrays
