Description
  • Řada reálných problemu je dynamická a dochází ke změnám problému. Cílem řešení problému minimálních změn je nalézt takové řešení nového problému, aby bylo reflektováno řešení puvodního problému i změny v definici problému. Práce navrhuje nový algoritmus iterativního dopředného prohledávání, který umožňuje významná zlepšení kvality řešení toho problému. Navržené metody byly prověřeny řešením rozsáhlého rozvrhovacího problému na Purdue university. (cs)
  • Many real-life problems are dynamic, with changes in the problem definition occurring after a solution to the initial formulation has been reached. A minimal perturbation problem incorporates these changes, along with the initial solution, as a new problem whose solution must be as close as possible to the initial solution. A new iterative forward search algorithm is proposed to solve minimal perturbation problems. Significant improvements to the solution quality are achieved by including new conflict-based statistics in this algorithm. The proposed methods were applied to find a new solution to an existing large scale class timetabling problem at Purdue University, incorporating the initial solution and additional input changes.
