Lazy constraints and user cuts in LP file format

CPLEX conforms to these rules about lazy constraints and user cuts in LP file format.

This rule is of interest only to advanced users.

It is possible to include pools of lazy constraints and user defined cuts in an LP file. A pool of lazy constraints or of user-defined cuts must not contain any quadratic constraints. For more about these concepts, see User-cut and lazy-constraint pools in the CPLEX User’s Manual.
