We introduce a new problem arising in small and mediumsized container terminals: the Two-Dimensional Pre-Marshalling Problem (2D-PMP). It is an extension of the well-studied Pre-Marshalling Problem (PMP) that is crucial in container storage. The 2D-PMP is particularly challenging due to its complex side constraints that are challenging to express and difficult to consider with standard techniqu...

The seismic resilience of a structure has been evaluated using peak ground acceleration (PGA). Ground motion parameters such as source characteristics, local site conditions are used to forecast the PGA motion. This paper aims develop an Artificial Neural Network (ANN) based model predict PGA. Here, hypocentral distance ( R h y p o ${R}_{hypo}$ ), shear wave velocity V s 30 ${V}_{s30}$ and mome...

Abstract The growing use of the Internet with its vulnerabilities has necessitated adoption Intrusion Detection Systems (IDS) to assure security. IDSs are protective systems that detect outsider infiltrations, unauthorised accesses and malfunctions occurring in computer networks. Intrusions can be detected reported network administrator by using various pieces information such as port scanning ...

This work combines local search with a variant of the Ant System metaheuristic recently proposed for partitioning problems with cardinality constraints. The Coloured Ant System replaces the classical concept of trail with p trails of different “colours”, representing the assignment of an element to one of the classes in the partition. We apply the method with promising results to the design of ...

Balancing bike sharing systems is an increasingly important problem, because of the rising popularity of this mean of transportation. Bike sharing systems need to be balanced so that bikes (and empty slots for returning bikes) are available to the customers, thus ensuring an adequate level of service. In this paper, we tackle the problem of balancing a real-world bike sharing system (BBSS) by m...

Constructive metaheuristics explore a tree of constructive decisions, the topology of which is determined by the way solutions are represented and constructed. Some solution representations allow particular solutions to be reached on a greater number of paths in this construction tree than other solutions, which can introduce a bias to the search. A bias can also be introduced by the topology o...

An improved method for adaptive noise canceller (ANC) is proposed for noisy speech signal in case of random noise. In this approach, ANC is implemented through four different metaheuristic techniques. A comparative study of the performance of various metaheuristic techniques such as Particle Swarm Optimization (PSO), Artificial Bee Colony (ABC), Cuckoo Search (CS) and Modified Cuckoo Search (MC...
