This measure increases in the minimal number of items over which a combinatorial search has to be performed before the remainder of the knapsack can be filled using the greedy algorithm and the optimal solution
The first, called Complete Greedy Algorithm (CGA), uses the Longest Processing Time heuristic (LPT), first introduced in Graham (1969); the second, called Complete Karmarkar-Karp Algorithm (CKK), uses the Differencing Method heuristic, better known as the Karmarkar-Karp Heuristic (KKH), ...
Knapsack formulation of the considered practical problem, and a novel solution procedure based on Lagrangian relaxation. The paper presents the results of computational experiments aimed at testing the optimisation procedure on real world data originating from Australia’s largest electricity distributor. ...
This method is inspired by the classical GWO and EGWO algorithms. In this algorithm is considered that the alpha wolf has best knowledge about the prey position and other wolves in the pack must follow alpha wolf in order. In this method, each wolf updates its position based on all the wo...
