You can switch the settings for all pre SOLVING, heuristics, and separation plugins to three different modes via the set {pre solving, heuristics, separation} emphasis parameters in the interactive shell. off TURNS off the respective TYPE of plugins, fast chooses settings that lead to less time spent in this type of plugins, decreasing their impact, and aggressive increases the impact of this type of plugins. You can combine these general settings for cuts, pre solving, and heuristics arbitrarily.

Display parameters shows you which settings currently differ from their default, set default resets them all. Furthermore, there are complete settings that can be set by set emphasis, i.e. settings for pure FEASIBILITY problems, solution counting, and CP like search.
