Initializing help system before first use

lpoptimize

Purpose
This function begins a search for the optimal continuous (LP) solution.
The direction of optimization is given by OBJSENSE. The status of the problem when the function completes can be checked using LPSTATUS. Any MIP entities in the problem will be ignored.
Synopsis
lpoptimize(prob, flags = "")
Arguments
prob 
The current problem.
flags 
Flags to pass to lpoptimize ( LPOPTIMIZE). The default is "" or NULL, in which case the algorithm used is determined by the DEFAULTALG control. If the argument includes:
b
the problem will be solved using the Newton barrier method, or the Hybrid gradient method if BARALG is set to 4;
p
the problem will be solved using the primal simplex algorithm;
d
the problem will be solved using the dual simplex algorithm;
n
(lower case N), the network part of the problem will be identified and solved using the network simplex algorithm;
Return value
The input argument prob.
