comment Solve Laplace equation using NDSolve
Aren't there conflicting boundary conditions? For instance, u[x,40] equals u[100,y] at {x,y}=={100,40} making you state 0==100 at that point.

comment Apply Collatz Funtion to solve and print the answer
Because the collatz procedure generates a tree and if you start in one branch you will miss numbers in other branches or which are higher up in your own branch.

comment Plotting a several variable complex valued function
That would require a 6D plot. For C -> C you could use 2D to 2D mappings. For this case I don't think you could do anything useful.

The Wikipedia article has various external links to existing Java and C libraries. I assume you could link those in Mathematica.
