On the aircraft conflict resolution problem: A VNS approach in a multiobjective framework

Antonio Alonso-Ayuso, Laureano Escudero, F Javier Martin-Campo, Nenad Mladenovic

The aircraft conflict resolution problem needs to provide response to such situation in which two or more aircraft violate the safety distances that must be kept during the flight. Then, given the aircraft trajectories, the aim consists of finding a new configuration such that every conflict…

The lock-in technique applied to heat exchangers: A semi-analytical approach and its application to fouling detection

Sylvain Lalot, Bernard Desmet

One of the current methods to detect fouling in heat exchangers is based on the analysis of the evolution of the effectiveness over time. The present results show that, using this kind of analysis, a 6% decrease of the overall heat transfer coefficient cannot be detected when measurement noise (±0.…

Less is more: Solving the Max-Mean diversity problem with variable neighborhood search

Jack Brimberg, Nenad Mladenovic, Raca Todosijević, Dragan Urošević

Within the broad class of diversity/dispersion problems we find an important variant known as the Max–Mean Diversity Problem, which requires finding a subset of a given set of elements in order to maximize the quotient of the sum of all edges belonging to that subset and the cardinality of the…

Process simulation and analysis of carbon capture with an aqueous mixture of ionic liquid and monoethanolamine solvent

Baptiste Zacchello, Eni Oko, Meihong Wang, Fethi Aloui

This study investigated the prospect of using aqueous mixture of 1-butylpyridinium tetrafluoroborate ([Bpy][BF4]) ionic liquid (IL) and monoethanolamine (MEA) as solvent in post-combustion CO2 capture (PCC) process. This is done by analysis of the process through modelling and simulation. In…

Characterisation and Parameters Identification of Materials Constitutive and Damage Models: From Normalised Direct Approach to Most Advanced Inverse Problem Resolution.

Eric Markiewicz, Bertrand Langrand

The paper aims at providing an overview of the research activities performed from the two past decades at the authors laboratory, in the field of the materials characterisation under dynamic loadings (i.e. from 10^-3 s^-1 to 10^+3 s^-1 for structural crashworthiness and impact applications) and the…

Simplified Log - Likelihood Ratio Calculation for Binary LDPC Codes

Latifa Mostari, Abdelmalik Taleb-Ahmed

Combining binary LDPC codes and high order constellations is a simple but effective way to improve the bandwidth efficiency. Since the binary LDPC codes require soft decisions as the input information, the constellation has to provide soft information calculated by Log-Likelihood Ratio (LLR) to it…

A basic variable neighborhood search heuristic for the uncapacitated multiple allocation p-hub center problem

Jack Brimberg, Nenad Mladenovic, Raca Todosijević, Dragan Urošević

The uncapacitated multiple allocation p-hub center problem (UMApHCP) consists of choosing p hub locations from a set of nodes with pairwise traffic demands in order to route the traffic between the origin-destination pairs such that the maximum cost between origin-destination pairs is minimum. It…

Variable neighborhood search variants for Min-power symmetric connectivity problem

A.I. Erzin, Nenad Mladenovic, R.V. Plotnikov

We consider the problem of optimal communication tree construction in a given undirected weighted graph. Such a problem occurs while minimizing the power consumption of data transmission in different distributed networks in the case when network elements are able to adjust their transmission ranges…

J-means and I-means for minimum sum-of-squares clustering on networks

Alexey Nikolaev, Nenad Mladenovic, Raca Todosijević

Given a graph, the Edge minimum sum-of-squares clustering problem requires finding p prototypes (cluster centres) by minimizing the sum of their squared distances from a set of vertices to their nearest prototype, where a prototype can be either a vertex or an inner point of an edge. In this paper…
