Initializing help system before first use

xpress.ctrl

Purpose

Internal object class used for the controls of an xpress.problem. The user can read and write controls for a problem, but cannot create objects of this class.


Example
The following example creates a problem and then reads and sets a few of its controls: 
import xpress as xp

p = xp.problem()

x = [p.addVariable() for _ in range(10)]

p.addConstraint(xp.Sum(x) >= 1)

print('miprelstop is currently", p.controls.miprelstop)

p.controls.miprelstop = 1e-7
p.controls.xslp_solver = 0

# An equivalent way to do the two lines above
p.setControl({'miprelstop': 1e-7, 'xslp_solver': 0})
