This is the gateway method that calls either solveLp() or solveNlp() as appropriate based on the corresponding option setting.

| void scsolver::SolveModelImpl::solveLp | ( | ) | [inline] |
This method takes model parameters from the dialog, constructs an internal representation of an LP model, chooses an algorithm, solves it, and in case a feasible solution is found it puts the solution back into the cells.

This method returns an algorithm object to use to solve a given LP model. While all this method does currently is simply return the pre-selected algorithm, in future this method may be used to pick a user-selected algorithm based on his/her settings.

Transform a LP model given in the cells into the standard format. This is done by setting the value of one of the decision variable cells to 1 and all the others to 0, and interpret the values of the objective function and constraint cells, and repeat it for every decision variable cell.
