Initializing help system before first use

problem.writeprtsol

problem.writeprtsol


Purpose
Writes the current solution to a fixed format ASCII file, problem_name .prt.
Synopsis
problem.writeprtsol(filename, flags)
Arguments
filename 
A string of up to 200 characters containing the file name to which the solution is to be written. If omitted, the default problem_name will be used. The extension .prt will be appended.
flags 
(optional) Flags for writeprtsol are:
write the LP solution instead of the current MIP solution.
Example
This example shows the standard use of this function, outputting the solution to file immediately following optimization:
p.read("myprob", "")
p.lpoptimize("")
p.writeprtsol("", "")
Further information
1. The fixed width ASCII format created by this command is not as readily useful as that produced by problem.writesol. The main purpose of writeprtsol is to create a file that can be sent directly to a printer. The format of this fixed format ASCII file is described in the Xpress Optimizer reference manual.
2. To create a prt file for a previously saved solution, the solution must first be loaded with the problem.readbinsol function.
