[Cmpl-tickets] [CMPL - COIN Mathematical Programming Language] #1: A possible bug

[Mike Steglich]

Hi,

This isn't a bug. For objective functions and constraints divisions are not permitted in the current version. Please use the opportunities of the parameters section to manipulate parameters. 
But is planned to allow such things in CMPLv2.0

Cheers,
Mike
