Removes a constraint from the model and updates the indices of subsequent constraints in provided collections. Args: con

Starts the solver in a separate thread. Useful for handling KeyboardInterrupts. Do not attempt to modify the model while the solver

convert string to lower-case, modifies string

Make a copy of the string and then trim it

Computes maximum alpha such that x + alpha*dx >= 0. The blocking index is returned in blocking_index if not NULL.
