1. Multi-step Generation of Bayesian Networks Models for Software Projects Estimations

Raquel Fuentetaja, Daniel Borrajo, Carlos Linares López, Jorge Ocón
Pages: 796 - 821
Software projects estimations are a crucial component of successful software development. There have been many approaches that deal with this problem by using different kinds of techniques. Most of the successful techniques rely on one shot prediction of some variables, as cost, quality or risk, taking...

3. New LMI-based Criteria for Lagrange Stability of Cohen-Grossberg Neural Networks with General Activation Functions and Mixed Delays

Xiaohong Wang, Huan Qi
Pages: 836 - 848
In this paper, the problem on Lagrange stability of Cohen-Grossberg neural networks (CGNNs) with both mixed delays and general activation functions is considered. By virtue of Lyapunov functional and Halanay delay differential inequality, several new criteria in linear matrix inequalities (LMIs) form...

5. Particle Swarm Optimizer with Aging Operator for Multimodal Function Optimization

Bo Jiang, Ning Wang, Xiaodong Li
Pages: 862 - 880
This paper proposes a new scheme for preventing a Particle Swarm Optimizer from premature convergence on multimodal optimization problems. Instead of only using fitness evaluation, we use a new index called particle age to guide population towards more promising region of the search space. The particle...

7. Using Multivariate Adaptive Regression Splines in the Construction of Simulated Soccer Team's Behavior Models

Pedro Henriques Abreu, Daniel Castro Silva, João Mendes-Moreira, Luís Paulo Reis, Júlio Garganta
Pages: 893 - 910
In soccer, like in other collective sports, although players try to hide their strategy, it is always possible, with a careful analysis, to detect it and to construct a model that characterizes their behavior throughout the game phases. These findings are extremely relevant for a soccer coach, in order...

8. Digital FIR Filter Design Using Hybrid Random Particle Swarm Optimization with Differential Evolution

Vasundhara, Durbadal Mandal, Sakti Prasad Ghoshal, Rajib Kar
Pages: 911 - 927
This paper presents a novel approach of designing linear phase FIR low pass and high pass filter using Random PSO in hybrid with DE known as Random PSODE (RPSODE). In this paper, the Random PSO is used which utilises the weighted particle to guide the search direction for both explorative and exploitative...

13. New Entropy, Similarity Measure of Intuitionistic Fuzzy Sets and their Applications in Group Decision Making

Xia Liang, Cuiping Wei, Meimei Xia
Pages: 987 - 1001
In this paper, we propose a new entropy measure with geometrical interpretation of intuitionistic fuzzy sets. Compared with the entropy measure provided by Szmidt and Kacprzyk, the new entropy formula in this paper can measure both fuzziness and intuitionism for intuitionistic fuzzy sets. According to...
