# var.getSolution

Purpose
Returns the primal value of this variable from the incumbent solution during or after optimization with problem.optimize, problem.mipOptimize, problem.lpOptimize or problem.nlpOptimize.
Topic areas
Solution, Optimizer
Synopsis
`x = var.getSolution()`
Return value

x | The solution value of the variable.

Further information
1. The function always returns data in the input space, even if the problem is currently in presolved state.
2. During a deterministic MIP solve, the incumbent solution is only available once it has been deterministically communicated to the current MIP worker problem.
3. During an SLP solve, the incumbent solution is not necessarily feasible. It is generally the best solution seen so far in terms of feasibility and the objective function, depending on the values of the SLPFILTER and NLPMERITLAMBDA controls.
