The path planning problem, i.e. the geometrical problem of finding a collision-free path between two given configurations of a robot moving among obstacles, has been studied by many authors in recent years. The interest in constrained motion planning is more recent. Constrained motion planning consists in finding motion sequences for robotic systems whose free space in not an open subset of the...

concerns regarding the trans-pacific partnership (tpp) have raised awareness about the negative public health impacts of trade and investment agreements. in the past decade, we have learned much about the implications of trade agreements for public health: reduced equity in access to health services; increased flows of unhealthy commodities; limits on access to medicines; and constrained policy...

in this article, a finite horizon, multi product and multi period economic order quantity like seasonal items is considered where demand rate is deterministic and known but variable in each period. the order quantities of items come in batch sizes and the end of the period order quantity and, consequently, demand of customers are zero. in addition, storage space is constrained and the problem ...

Constrained Willmore surfaces are conformal immersions of Riemann surfaces that are critical points of the Willmore energy W = R H 2 under compactly supported infinitesimal conformal variations. Examples include all constant mean curvature surfaces in space forms. In this paper we investigate more generally the critical points of arbitrary geometric functionals on the space of immersions under ...

Sundance is a package in the Trilinos suite designed to provide high-level components for the development of highperformance PDE simulators with built-in capabilities for PDE-constrained optimization. We review the implications of PDE-constrained optimization on simulator design requirements, then survey the architecture of the Sundance problem specification components. These components allow i...

5 Movement for many animal species is constrained in space by barriers such as rivers, shore6 lines, or impassable cliffs. We develop an approach for modeling animal movement con7 strained in space by considering a class of constrained stochastic processes, reflected stochas8 tic differential equations. Our approach generalizes existing methods for modeling uncon9 strained animal movement. We p...

In this paper, we present constrained simulated annealing (CSA), a global minimization algorithm that converges to constrained global minima with probability one, for solving nonlinear discrete non-convex constrained minimization problems. The algorithm is based on the necessary and suucient condition for constrained local minima in the theory of discrete Lagrange multipliers we developed earli...

The aim of this article is to develop the basics of a theory of constrained Willmore surfaces. These are the critical points of the Willmore functional W = ∫ H 2 dA restricted to the class of conformal immersions of a fixed Riemann surface. The class of constrained Willmore surfaces is invariant under Möbius transformations of the ambient space. Examples include all constant mean curvature surf...
