Introduction

pyosi allows you to use COIN-OR's Open Solver Interface, aka OSI, from python.

What you'll be able to perform with pyosi is something like the following code:

import pyOSI

theSI = pyOSI.getOsiClp()

#Read in an mps file.  This one's from the MIPLIB library.
theSI.readMps("p0033")

#Solve the (relaxation of the) problem
theSI.initialSolve()

#Check the solution
if ( theSI.isProvenOptimal() ):
       print "Found optimal solution!"
       print "Objective value is %f" % theSI.getObjValue()
       n = theSI.getNumCols()
       solution = theSI.getColSolution()
       for i in solution:
             print i

else:
       print "Didn't find optimal solution."

pyosi was written using the boost.python library.
