Meta-heuristics support managers in decision-making with robust tools that provide high-quality solutions to important applications in business, engineering, economics and science in reasonable time horizons. In this paper we give some insight into the state of the art of meta-heuristics. This primarily focuses on the significant progress which general frames within the meta-heuristics field ha...

PYRROS is a tool for scheduling and parallel code generation for distributed memory message passing architectures [35]. In this paper, we discuss several compile-time optimization techniques used in PYRROS. The scheduling part of PYRROS optimizes both data and program mapping so that the parallel time is minimized. The communication and storage optimization part facilitates the generation of e ...

Vve address the problem of scheduling observations for a collection of earth observing satellites. This scheduling task is a difficult optimization problem, potentially involving many satellites, hundreds of requests, constraints on when and how to service each request, and resources such as instruments, recording devices, transmitters, and ground stations. High-fidelity models are required to ...

Register allocation and instruction scheduling are two central compiler back-end problems that are critical for quality. In the last two decades, combinatorial optimization has emerged as an alternative approach to traditional, heuristic algorithms for these problems. Combinatorial approaches are generally slower but more flexible than their heuristic counterparts and have the potential to gene...

This paper presents a multi-objective resource-constrained project scheduling problem with positive and negative cash flows. The net present value (NPV) maximization and making span minimization are this study objectives. And since this problem is considered as complex optimization in NP-Hard context, we present a mathematical model for the given problem and solve three evolutionary algorithms;...

Today's competitive conditions have caused the projects to be carried out in the least possible time with limited resources. Therefore, managing and scheduling a project is a necessity for the project. The timing of a project is to specify a sequence of times for a series of related activities. According to their priority and their latency, so that between the time the project is completed and ...
