Detailed Description
A vector field with constraints s.t. ci(x) >= 0.
The value ci(x) represents the "margin" of the constraint. There's an issue of scale, and in general it is nice to have |grad(ci(x))| ~= 1 near the boundaries, so the margin is roughly the distance to the boundary.
Member Function Documentation
Given x0 feasible, finds a maximal value u<=u0 s.t. x=x0+u*dx satisfies the constraint. i version: only satisfy the i'th constraint. j version: move in the direction ej. (default uses secant method)
