stop causes a break, the user is asked whether to continue or not. fixed entries are displayed in red colour; the grey numbers show the algorithm in action. date and time are displayed when the computation starts and when the computation ends. the solution number and the last found solution are displayed. stop at next solution causes a break, when the next solution is found. |
