Since 1973 technological, political, regulatory, and economic forces have been changing the worldwide economy in a fashion comparable to the changes experienced during the nineteenth century Industrial Revolution. As in the nineteenth century, we are experiencing declining costs, increaing average (but decreasing marginal) productivity of labor, reduced growth rates of labor income, excess capacity, and the requirement for downsizing and exit. The last two decades indicate corporate internal control systems have failed to deal effectively with these changes, especially slow growth and the requirement for exit. The next several decades pose a major challenge for Western firms and political systems as these forces continue to work their way through the worldwide economy.

This book presents a unified treatment of many different kinds of planning algorithms. The subject lies at the crossroads between robotics, control theory, artificial intelligence, algorithms, and computer graphics. The particular subjects covered include motion planning, discrete planning, planning under uncertainty, sensorbased planning, visibility, decisiontheoretic planning, game theory, information spaces, reinforcement learning, nonlinear systems, trajectory planning, nonholonomic planning, and kinodynamic planning.
A Heuristic Algorithm for the Rectilinear Steiner Arborescence Problem
 Engineering Optimization
, 1994
"... In this paper the following problem is considered: given a root node R in a mesh and a set D of nodes from the mesh, construct a shortestpath tree rooted at R that spans the set D and minimizes the number of links used. The problem is equivalent as finding a Steiner tree in a directed mesh in whic ..."

in which all the links point away from the root node R. The problem of finding a Steiner tree in such grid has been known in the literature as the Rectilinear Steiner Arborescence (RSA) problem. Rao et. al [9] have proposed an efficient heuristic algorithm for a special case of this problem, in which all
On the Construction of Optimal or NearOptimal Rectilinear Steiner Arborescence
, 1994
"... Given a set of nodes N lying on the first quadrant of the Euclidean Plane E 2 , the Rectilinear Minimum Steiner Arborescence (RMSA) problem is to find a shortestpath tree of the minimum length rooted at the origin, containing all nodes in N , and composed solely of horizontal and vertical arcs or ..."

"... The Symmetric Rectilinear Steiner Arborescence (SRStA) problem is defined as follows: given a set of terminals in the positive quadrant of the plane, connect them using horizontal and vertical lines such that each terminal can be reached from the origin via a ymonotone path and the total length o ..."

Rectilinear Steiner trees with minimum Elmore delay
 PROC. DESIGN AUTOMATION CONF
, 1994
"... We provide a new theoretical framework for constructing Steiner routing trees with minimum Elmore delay. Earlier work [3, 13] has established Elmore delay as a high fidelity estimate of "physical", i.e., SPICEcomputed, signal delay. Previously, however, it was not known how to construct a ..."

Our main theoretical result is a generalization of Hanan's theorem [11] which limited the number of possible locations of Steiner nodes in an optimal delay rectilinear Steiner tree. Another theoretical result establishes a new decomposition theorem for constructing

The field of metaheuristics for the application to combinatorial optimization problems is a rapidly growing field of research. This is due to the importance of combinatorial optimization problems for the scientific as well as the industrial world. We give a survey of the nowadays most important metaheuristics from a conceptual point of view. We outline the different components and concepts that are used in the different metaheuristics in order to analyze their similarities and differences. Two very important concepts in metaheuristics are intensification and diversification. These are the two forces that largely determine the behaviour of a metaheuristic. They are in some way contrary but also complementary to each other. We introduce a framework, that we call the I&D frame, in order to put different intensification and diversification components into relation with each other. Outlining the advantages and disadvantages of different metaheuristic approaches we conclude by pointing out the importance of hybridization of metaheuristics as well as the integration of metaheuristics and other methods for optimization.
