Posts new subproblem solution(s) to the colgen instance ColgenInstance.
Subproblem solution (sp_sol structure) or list of subproblem solutions


Post subproblem solution(s) corresponding to a column of coefficients for a new master problem variable to the colgen instance ColgenInstance. The argument must be a sp_sol structure or list of such structures:

      sp_sol(cost, coeff_vars, aux)
where cost is the master problem cost function coefficient of the solution, coeff_vars is a list of Id-Val pairs corresponding to the subproblem variable solution values and identifier of the constraint in which it occurred as an implicit sum term for those subproblem variables with a non-zero solution value. aux should contain any problem specific information which is of interest that is not represented uniquely by the cost and objective coefficients.
