Follow-up Comment #6, bug #22554 (project relax): Even with constraints on, and simplex as minimisation it seems that simplex takes a catastophic step, and get "inf" from the C-code. It is known, that minfx cannot handle 'inf' values, and terminates right away. x0 [ 1.035066856592987 1022.443240712164652] [ 1.017439782586841e+00 2.029754497891464e+03] 0.840053982988 846 1907 0 0 None Log barrier [[ 1. 0.] [-1. 0.] [ 0. 1.]] [ 0. -200. 0.] Simulation 1 x0 [ 1.035066856592987 1022.443240712164652] [ 1.037245769846418e+00 2.041876765235998e+03] 1.24717371552 743 1722 0 0 None Log barrier [[ 1. 0.] [-1. 0.] [ 0. 1.]] [ 0. -200. 0.] Simulation 2 x0 [ 1.035066856592987 1022.443240712164652] [ 1.037824582507327e+00 2.047667399532010e+03] 4.2070590787 738 1675 0 0 None Log barrier [[ 1. 0.] [-1. 0.] [ 0. 1.]] [ 0. -200. 0.] Simulation 3 _______________________________________________________ Reply to this item at: <http://gna.org/bugs/?22554> _______________________________________________ Message sent via/by Gna! http://gna.org/
