[Coin-lpsolver] Assert Problems

[John J Forrest]

Kyle,

The asserts have been modified to give an error message (bad format of 
input image).  The reason was that on output values of > 1.0e40 are output 
as blank.  This was a cheap fix for bounds but should not apply to 
elements or objective. The large values should now be output approximately 
correctly - as Senator Everett Dirkson said - 1.0e40 here and 1.0e40 there 
and soon you are talking real money!

Re: [Coin-lpsolver] Assert Problems






In addition to the problems mentioned below, trying to use an outputted 
mpsfile from the same experiment, I ran clp (the test program in the 
clp directory), and got the following assertion.

CoinMpsIO.cpp:669: failed assertion `after>next'

Any thoughts as to what problems might cause this sort of behavior? 
I'm sure it's my own fault, I'm just trying to narrow down the causes.
