baryonyx v0.3.3 - 2018-10-04 main: * output: better render output float number solver/optimizer: * Fix the preference matrix assignment for both equalities and inequalities with -1 and 1 coefficients, we replace the preference matrix clean up algorithm (invert the variable values for negative coefficients) with a version that revert only the added or subtracted value during the preferences update process. * Fix core dump if no solution are found preprocessor: * update the preprocessing solver option: Replace the old preprocessing option with new one but without description (p1, p2, p3 and p4). Options are `none` to use the raw problem (or lp file) order for constraints and variables. `memory`, the default, to use the raw problem (or lp file) order for constraints but sort the variables to improve the memory cache efficiency.
