Initializing help system before first use

problem.loadLPSol

Purpose
Loads an LP solution for the problem into the Optimizer.
Topic areas
Solution, LP, Data Input
Synopsis
status = problem.loadLPSol(x=None, slack=None, duals=None, djs=None)
Arguments
x 
Optional: Double array of length COLS (for the original problem and not the presolve problem) containing the values of the variables. May be None, see further information.
slack 
Optional: double array of length ROWS containing the values of slack variables. May be None, see further information.
duals 
Optional: double array of length ROWS containing the values of dual variables. May be None, see further information.
djs 
Optional: double array of length COLS containing the values of reduced costs. May be None, see further information.
Return value
status 
The status. The status is one of:
0 
Solution is loaded.
1 
Solution is not loaded because the problem is in presolved status.
Further information
1. If neither variable values nor dual values are provided, the current solution in memory will be unloaded.
2. When variables x is None, the variables will be set to their bounds.
3. When slack variables slack is None, it will be computed from variables x. If slacks are provided, variables cannot be omitted.
4. When dual variables duals is None, both dual variables and reduced costs will be set to zero.
5. When reduced costs djs is None, it will be computed from dual variables duals. If reduced costs are provided, dual variables cannot be omitted.
