Complexity: O(NW) UPD: If you know nothing about monotone queue, check google. The algorithm would be: insert x:B.push(x);sumB[topB]=sumB[topB-1]+x erase:ifnotA.hasElements():A=reverse B;construct sumA;B.clear();A.pop();query:returnsumA[topA]+sumB[topB];...

Frieze and Clarke [79] gave a PTAS for d-dimensional knapsack using the dual simplex algorithm for LP. Subsequently, Caprara et al. [174] gave a scheme with improved running time of O(n⌈d/ε⌉−d). However, there is no EPTAS even for 2-D vector knapsack [80], unless W[1...
The space requirement of the DP algorithm is O(c+ϵ). The running time complexity is O(n(c+ϵ)), with n being the total number of items. Results and discussion To evaluate our method, we conducted a leave-one-out-analysis using a snapshot of the ATB database containing roughly ...
Analysised of the complexity of the algorithm and implementation results showed that the designed algorithm is effective and feasible. This algorithm can be extended to solve other NPC problems, such as TSP problemYan-Hua ZhongShu-Zhi Nie
We analyze the competitive ratio and the advice complexity of the online unbounded knapsack problem. An instance is given as a sequence of n items with a size and a value each, and an algorithm has to decide whether or not and how often to pack each item into a knapsack of bounded capac...
Lattice Reduction for Modular Knapsack 279 This algorithm is therefore named L2. This algorithm makes use of floating-point arithmetics, hence, the library that implements L2 is sometimes referred to as fplll [23]. It terminates with a worst-case time complexity of O(d4+εβ2 + d5+εβ...
