You say vb is a programming language, and c++ and java are both programming languages, but the mathematical modeling contest uses special software to build models, and you can get the results you want by analyzing the models. Matlab and lingo are just two of them, and Mathematica is also a software for mathematical modeling. Quite a few. Learning depends on one's learning ability and understanding ability. I suggest going to China Mathematics Forum, where there are many tutorials and award-winning papers. Learn while watching, and you will soon understand what mathematical modeling is all about. Baidu ranked first in mathematics in China.
