Searching the internet for an example of backtracking in VB.Net has proven fruitless. All the examples I found were either in a language I don't understand (making it impossible for me to convert it to vb.net) or they contained zero commenting (making it difficult to actually understand what is going on).

Does anyone have an example of backtracking in VB.Net? Commenting would be useful so I don't have to decipher single letter variables.
