Initializing help system before first use

tune

Purpose
This function begins a tuner session for the current problem.
The tuner will solve the problem multiple times while evaluating a list of control settings and promising combinations of them. When finished, the tuner will select and set the best control setting on the problem. Note that the direction of optimization is given by OBJSENSE.
Synopsis
tune(prob, flags = "")
Arguments
prob 
The current problem.
flags 
Flags to pass to tune, which specify whether to tune the current problem as an LP or a MIP problem, and the algorithm for solving the LP problem or the initial LP relaxation of the MIP. The flags are optional. If the argument includes:
l
will tune the problem as an LP (mutually exclusive with flag g);
g
will tune the problem as a MIP (mutually exclusive with flag l);
x
will tune the problem as a Global Optimization problem with Xpress Global;
d
will use the dual simplex method;
p
will use the primal simplex method;
b
will use the barrier method;
n
will use the network simplex method.
Return value
The input argument prob.
