Is it possible to refine how much information is provided in the Xpress Optimiser Logs

I currently use XPRS_VERBOSE to switch between full logging of the optimisation process and essentially no logging. Is it possible to control (i.e. reduce) how much output is written during logging without adding my own write statements to do the same job?

    Hi Colin,

    depending on which type of problem you are solving, you should be able to control the amount of logging produced during the solve by setting one of the Optimizer controls

    XPRS_LPLOG

    XPRS_MIPLOG

    XPRS_NLPLOG

    There are also a few more granular controls listed on the logging overview page: https://www.fico.com/fico-xpress-optimization/docs/latest/solver/optimizer/HTML/chapterTopics.html?scroll=secoptimizertopics-Logging
