Multivariate time series analysis for short-term forecasting of ground level ozone (O3) in Malaysia [PDF]

open access: yes, 2021
The declining of air quality mostly affects the elderly, children, people with asthma, as well as a restriction on outdoor activities. Therefore, there is an importance to provide a statistical modelling to forecast the future values of surface layer

Effective heuristics and meta-heuristics for the quadratic assignment problem with tuned parameters and analytical comparisons [PDF]

open access: yes, 2012
Quadratic assignment problem (QAP) is a well-known problem in the facility location and layout. It belongs to the NP-complete class. There are many heuristic and meta-heuristic methods, which are presented for QAP in the literature.

Meta heuristics for the orienteering problem

open access: yesProceedings of the 2002 Congress on Evolutionary Computation. CEC'02 (Cat. No.02TH8600), 2003
This paper presents two meta-heuristic techniques, ant colony optimization and tabu search, for the orienteering problem, a general version of the well-known traveling salesman problem with many relevant applications in industry. Both algorithms are compared to other heuristics in the literature.

Jamming Model for the Extremal Optimization Heuristic [PDF]

open access: yes, 2001
Extremal Optimization, a recently introduced meta-heuristic for hard optimization problems, is analyzed on a simple model of jamming. The model is motivated first by the problem of finding lowest energy configurations for a disordered spin system on a ...
