Research ArticleOpen accessIn the abstractQuadratic Convergence Ratio of Constrained Optimal Control ProblemsO. OlotuProblem statement: Earlier Researchers developed algorithms for solving quadratic control problems, but did not address the quadratic convergence ratio profile. Approach: Hence, the objective of this work is using our developed scheme, Discretized Continuous Algorithm (DCA), to examine both convergence profile and quadratic ratio profile demonstrating the effectiveness and efficiency of the scheme. Methodologically, we obtained generalized unconstrained formulation of … …Journal of Mathematics and Statistics, Vol. 6, Issue 1 · 31 Mar 2010 · 7,372 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImbedding the Multiplier in a Discretized Optimal Control Problem With Real Coefficients Via the Penalty and Multiplier MethodsO. OlotuProblem statement: Many earlier schemes, particularly the Function Space Algorithm (FSA) which sidetracks the knowledge of operator, for solving quadratic optimal control problems have been computationally involving and iteratively high. Approach: Though, some of these earlier schemes developed operators consisting of complicated integrals still very difficult to evaluate. Here, objectively, a new scheme, Discretized Continuous Algorithm (DCA), is proposed with … …Journal of Mathematics and Statistics, Vol. 6, Issue 1 · 31 Mar 2010 · 7,041 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effects of North America Free Trade Agreement on Mexican Environmental Policy (1994-2004)Ningu J. Kenneth, Jorge Torres Jácome, Sonia E.S. Gomez, Pérez ÁvilesThe scope of this study was to analyze the implementation of the environmental policy and the way Mexico has integrated the environmental aspects into a North America Free Trade Agreement (NAFTA). We are aware of the fact that many environmental costs do not necessarily reflect the environmental damage. Environmental costs are often defined by determining either the willingness of the … …American Journal of Environmental Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 6,357 accessesView PDF Cite
