# ColgenInstance:cg_subproblem_solution(++Value)

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

## Description

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.
