the optimized time-complexity O(n/p log(2)p + C'/p) by our parallel time-space reduction. In this new approach, we integrate the FS method (for the efficient initial solutions) and the optimal DP (on the remaining critical-objects n' and knapsack-capacity C'), incorporated with the ...
In this paper, we present a rigorous running time complexity analysis for the algorithm on two simple discrete pseudo boolean functions and on the multiobjective knapsack problem which is known to be NP-complete. We use two well known simple functions LOTZ (Leading Zeros: Trailing Ones) and a...
The below is the implementation of merge sort using C++ program: #include <iostream>usingnamespacestd;inttemp[10000];voidmergearrays(intar[],ints,inte) {intmid=(s+e)/2;inti, j; i=s; j=mid+1;intx=s;while(i<=mid&&j<=e) {if(ar[i]<ar[j]) { temp[x++]=ar[i]; ...
Bubble sort's time complexity in both of the cases (average and worst-case) is quite high. For large amounts of data, the use of Bubble sort is not recommended.The basic logic behind this algorithm is that the computer selects the first element and performs swapping by the adjacent ...
and thus its time-space-processor tradeoff isO(n27n/8). The performance analysis and comparisons show that the proposed algorithms are both time and space efficient, and thus is an improved result over the past researches. Since it can break greater variables knapsack-based cryptosystems and ...
We give a deterministic, polynomial-time algorithm for approximately counting the number of {0,1}-solutions to any instance of the knapsack problem. On an instance of length n with total weight W and accuracy parameter eps, our algorithm produces a (1 + eps)-multiplicative approximation in ...
0-1-kiapsack problemIn this study, designed a O(n2log2n) quantum mechanical algorithm, to solve the 0-1-knapsack problem on a hypothetical quantum computer. Used the special characteristics of the quantum environment, constantly divided the state of vector space, reduced the probability of ...
However, alternating method is with high complexity and might not lead to a true optimal solution [6]. How to optimize locations of sinks and routes from sensors to sinks simultaneously is clearly important but challenging. In this paper, we will study this problem and develop efficient method ...
1 Introduction Given a (multi) set S of n positive integers and an integer target value u, the subset sum problem is to decide if there is a subset of S that sums up to u. The subset sum is a special case of the knapsack problem [14] and it is one of Karp's original NP-...
