The greedy algorithm obviously fills the knapsack at least half. The competitive ratio is then at most (2/3)/(1/2)=4/3. In order to prove a lower bound, let 0<ε<1/2 and we consider n−1 different instances I2,…,In where Ik=(13+ε,13+ε2,13+ε3…,13+εk−2,13+ε...

Other methods can be used such as genetic algorithms, greedy algorithms or algorithms based on BB (branch and bound). 4.2.3.2 Resolution algorithm For this algorithm, we will use the following variables: – C, maximum capacity of the knapsack; – i, increment of the line of the table; –...
In the greedy algorithm, items are ranked in descending order of their ratio of value over weight, and the knapsack is filled in this order until capacity is reached. The ranking will be less accurate if values and weights are more highly correlated. When correlation is perfect (as in our ...

We focus on obtaining approximate solutions in polynomial computational time. We show that simple greedy approaches yield 1/3-approximation algorithms for the objective of maximizing assigned weight. We give two different 1/2-approximation algorithms: the first one solves single knapsack problems successi...
Therefore, interest in the application of the metaheuristic algorithms has become necessary to solve these problems and obtain the results in a reasonable time [19–22]. The 0–1 KP can be solved also by greedy genetic algorithm (GA), GA, and rough set theory and ant weight-lifting ...
The 0/1 knapsack polytope is the convex hull of all 0/1 vectors that satisfy a given single linear inequality with non-negative coefficients. This paper pr
