Hi,

I use cplex in java for solving text summarizing model. My purpose is not the objective maximized sum, but one of boolean arrays i define as part of constraints. I faced with the problem that for some specific texts I just get "The referenced IloExtractable has not been extracted by the IloAlgorithm" exception when trying to get value of this array, after ensuring cplex.solve(). Looks like model data is right and model works good for most texts. What can be a problem?

Thanks in advance

Does this technote help?  Also, there are a few related forum posts on this (e.g., try the "This Forum" search above).
