Several Methods of Analysis for Cardinality Constrained Bin Packing,?1] are to be packed into bins, such that no bin has more than . items or total size larger than 1. The goal is to minimize the number of bins..A recently introduced concept, called the price of clustering, deals with inputs that are presented in a way that they are split into clusters. Thus, an ite

Improved Online Algorithm for Fractional Knapsack in the Random Order Model,er, the corresponding online setting has been handled only briefly in the theoretical computer science literature so far, although it appears in several applications. Even the previously best known guarantee for the competitive ratio was worse than the best known for the integral problem in the popu

For the basic Precedence-Constrained Knapsack problem (PCKP) we answer an open question of McCormick et al. [.] and show the existence of approximation algorithms with strongly-polynomial b
