[Coin-discuss] reading of SOS in lp files from CPLEX

[Kish Shen]

Hi,

I am getting errors from Cbc when reading an LP format file generated by
CPLEX 12:

### CoinLpIO::readLp(): bad SOS item S1

I assume this is from reading the SOS items in the LP file:

 s999:  S1 ::  x1154 : 1  x5539 : 2

Looking at CoinLpIO.cpp, the code expects no space between S1 and ::

            if
(next>=buff&&(!strncmp(next,"S1::",4)||!strncmp(next,"S2::",4))) {
              setType = next[1]-'0';
              gotStart=true;
            } else {
              // error
              goodLine=0;
            }

Should this be fixed to allow more flexibility in reading SOS items?

I am running the latest stable branch of Cbc 2.9, downloaded via svn co
about 2 days ago.

Thanks and cheers,

Kish
