Node Depth Encoding for Evolutionary Algorithms applied to Degree constrained minmum spanning tree problem

Hello , I am Pham Van Thang. I am a student at Hanoi University of Technology.
I am researching on Node Depth Encoding for Evolutionary Algorithms applied to Network Problem.I am currently coding Node Depth Encoding for Evolutionary Algorithms applied to Degree constrained minmum spanning tree problem or applied to Bounded diameter minmum spanning tree problem. But I'm not good at programming. Can you help me for programming ?
