I have the most recent version of COIN, I believe. I nevertheless have
trouble reading some mps files. This is similar to Anureet's problem
a few weeks ago. When reading the file
splittable.flow.network.design/ns25/pr3.mps
from the collection arcset.data.mps.gz available from
http://ieor.berkeley.edu/~atamturk/data/arcset/
using:
OsiClpSolverInterface *clp = new OsiClpSolverInterface;
clp->readMps(name, "mps");
I get:
Coin0001I At line 1 NAME pr3
Coin0001I At line 2 ROWS
Coin0001I At line 2214 COLUMNS
Coin0001I At line 36804 RHS
Coin0001I At line 36990 BOUNDS
Coin3006W No match for column C8541 0 at line 45531 < LI BOUND C8541 0 >
Coin3006W No match for column C8542 0 at line 45532 < LI BOUND C8542 0 >
Coin3006W No match for column C8543 0 at line 45533 < LI BOUND C8543 0 >
Coin3006W No match for column C8544 0 at line 45534 < LI BOUND C8544 0 >
Coin3006W No match for column C8545 0 at line 45535 < LI BOUND C8545 0
...
and then a crash. Does CoinMpsIO support these LI bounds or not? What change
should I make to read these files with OsiClp?
