[Coin-discuss] Re: initialSolve

[Anureet Saxena]

dear sir,
   
  Thank you very much for your reply. I would have never figured out this issue myself, so thanks again. 
   
  It would be very nice if we can adapt this feature as part of COIN.
   
  regards,
  anureet

Anureet,

Cplex seems to accept a non standard MPS format bound.  There are LI bounds
which I have never heard of (they obviously allow a lower bound of minus
infinity).  The Mps standard is MI and when I changed them to that then the
problem was feasible.

CoinMpsIo should have given error messages on unrecognized bound types - I
think I have corrected that.
