[Coin-lpsolver] OsiClp::deleteCols

[Anureet Saxena]

hi,
   
  I am using OsiClpSolverInterface to construct a mixed integer program. There seems to be some problem with the deleteCols(int,int*) function; the code does not seem to update the information about the integer variables properly. A simple code with a 3-variable 1-constraint example to reproduce this problem is available at:
   
  http://www.andrew.cmu.edu/user/anureets/tmp/deleteCols.tgz
   
  Of the three (x,y,z) variables in the test problem only y is integer constrained. However after deleting the variable x from the problem, the modified problem has z as the integer constrained variable.
   
  It will be very helpful if someone could fix this problem.
   
  regards & thanks,
  Anureet Saxena
