Optimizing constrained problems through a T-Cell artificial immune system
(Universidad Nacional de La Plata. Facultad de Informática, 2008-10)
In this paper, we present a new model of an artificial immune system (AIS), based on the process that suffers the T-Cell, it is called T-Cell Model. It is used for solving constrained (numerical) optimization problems. The ...
Error analysis of generalized-alpha Lie group time integration methods for constrained mechanical systems
(Springer, 2015-01)
Generalized-α methods are very popular in structural dynamics. They are methods of Newmark type and combine favourable stability properties with second order convergence for unconstrained second order systems in linear ...
Solving constrained optimization using a t-cell artificial immune system
(Asociación Española para la Inteligencia Artificial, 2008-10)
In this paper, we present a novel model of an artificial immune system (AIS), based on the process that suffers the T-Cell. The proposed model is used for solving constrained (numerical) optimization problems. The model ...
Artificial immune system for solving constrained optimization problems
(Sociedad Iberoamericana de Inteligencia Artificial, 2007-10)
In this paper, we present an artificial immune system (AIS) based on the CLONALG algorithm for solving constrained (numerical) optimization problems. We develop a new mutation operator which produces large and small step ...
A quasi-Newton modified LP-Newton method
(Taylor & Francis Ltd, 2017-10)
We consider a method to solve constrained system of nonlinear equations based on a modification of the Linear-Programming-Newton method and replacing the first-order information with a quasi-Newton secant update, providing ...
Efficient on-board Stereo SLAM through constrained-covisibility strategies
(Elsevier Science, 2019-06)
Visual SLAM is a computationally expensive task, with a complexity that grows unbounded as the size of the explored area increases. This becomes an issue when targeting embedded applications such as on-board localization ...
Lagrangian reduction of generalized nonholonomic systems
(Elsevier Science, 2008-10)
In this paper we study the Lagrangian reduction of generalized nonholonomic systems (GNHS) with symmetry. We restrict ourselves to those GNHS, defined on a configuration space Q, with kinematic constraints given by a general ...
On the local and superlinear convergence of a Secant Modified Linear-Programming-Newton Method
(Springer/Plenum Publishers, 2019-03-15)
We present a superlinearly convergent method to solve a constrained system of nonlinear equations. The proposed procedure is an adaptation of the linear-programming-Newton method replacing the first-order information with ...
An extension of the Dirac and Gotay-Nester theories of constraints for Dirac dynamical systems
(American Institute of Mathematical Sciences, 2014-06)
This paper extends the Gotay-Nester and the Dirac theories of constrained systems in order to deal with Dirac dynamical systems in the integrable case. Integrable Dirac dynamical systems are viewed as constrained systems ...
A derivative-free method for solving box-constrained underdetermined nonlinear systems of equations
(Elsevier Science Inc, 2012-11)
A derivative-free iterative method for solving bound-constrained underdetermined nonlinear systems is presented. The procedure consists of a quasi-Newton method that uses the Broyden update formula and a globalized line ...
