However, many theoretical constructions providing asymptotically optimal bounds are unusable in practise because of the very large constants involved.

When the objective is to minimize the total number of wavelengths used, this problem is NP-hard. The current state-of-the-art heuristics were proposed in 2007 by Sk混合,搀杂 发表于 2025-3-23 23:52:17

The problem of minimizing peak charges was recently introduced as an online problem in , which gave optimally competitive algorithms. In this problem, a battery (previously assumed to be perfectly efficient) is used to store energy for later use. In this paper, we extendNICE 发表于 2025-3-24 09:14:44

Perceptions of Crime and the Fear of Crime,One goal is to meet as closely as possible professors’ preferences. Building on an intuitive integer program (IP), we develop an exact decomposition approach which schedules courses first, and matches courses/times to rooms in a second stage. The subset of constraints which ensures a feasible room a蛛丝 发表于 2025-3-24 22:41:00
