An asterisk (*) at the beginning ofa line causes the entire line to be ignored. Otherwise, the line will be interpreted as an option name and valueseparated by any amount of white space (blanks or tabs).Following is an example options file cplex.opt.scaind 1simdisplay 2It will cause Cplex to use a more aggressive scaling method than the default. The iteration log will have an entryfor each iteration instead of an entry for each refactorization.
