RE: Simplex Method updated to V19(cas mode)
Hi,
Simplex program is updated to V19. Below are the new features. 1) Mixed Integer Continuous and Binary [0,1] Solution Example: Max: 0.043X1+0.027X2+0.025X3+0.022X4+0.045X5 S.T. X1 + X2 + X3 + X4 + X5 <= 10 X2 + X3 + X4 >= 4 0.6X1+ 0.6X2 - 0.4X3 - 0.4X4 + 3.6X5 <= 0 4X1 + 10X2 - X3 - 2X4 - 3X5 <= 0 X1 is integer, X3 is binary, others are continuous number. Solution = { 3 , 0 , 1 , 5.75 , 0.25 } 2) Target Z: You can specify a value for Z. Z=no target value, "<=", ">=" or "=" with target value. 3) Mixed branch and cut method for integer solution. May be I am not program it right, this method seems not reliable. Sometimes it can not provide the optimal solution. B&B is most reliable. 4) Allow re-edit and save data. This program use argument to save and reload data. sim19(0): "0" zero, for clean input, no previous data. sim19(1): always reload previous data. sim19(2), sim19(3),sim19(4)....: save equation data into the file"2","3","4"... . type sim19(2) to reload file"2" data. If you want to copy previous data to "4", just type reeditbag(4):=reeditbag(1) in cas mode. 5) fix a bug Regards, |
