I have following problem to solve:

I have to find shortest path in 3D space( grid ) using Genetic algorithm...I find some solution on the web:

but my problem is more complex – the fitness function will take (gravity = 9.81 * heigth ) at each point of the path...so the solution that i found on the web is probably wrong ?

Im wondering how to repesent the chromosm ?

Can sombody give my some advice how to solve the problem ?

Sorry for my english I am form Germany.

One solution that i found is that but this solution is probably wrong ...
