Is there a simplex-like algorithm that can be used with a separation oracle?

I'm not sure if you would consider the algorithms I'll discuss here "Simplex-like" (but see the comment about column generation at the end). If you have a weak separation oracle for a ...

Complexity of simplex method

It could be that the variants refer to two different forms of Linear Programs. Simplex only works with problems in Standard Equality Form (SEF) which is of the form $$\min c^T x\,\,\,\,\text{s.t.}\,\,\...

Enumerate all allocations of points in a simplex

I'd suggest using a recursive search. Suppose you have a subset of $k$ of the points and a proposed allocation for those $k$ points into X/Y/Z. Then you can test whether there exists $w_x,w_y,w_z$ ...
