DynamicMethod

Can't figure out why this DynamicMethod so much slower than the native c# method.

17 Nov 2012 by Alan N

I modified your code slightly so that it could be compiled using all .NET versions.With .NET2 and 3.5 there was no difference in execution time between the standard and dynamic methods, both taking about 1400 - 1500ms in release mode.However .NET 4 (v4.0.30319) was a different story...

Cutting rod implementation in C++?

You have an out of bound array access at b[i]. The array has a size of 9 items (max. allowed index is 8) but you are accessing index 9 within your loop (last i is n+1 = 9).I don't know the cutting rod algorithm. But you might have to either change the b array or use b[i-1].
