Algorithms For Discounted Stochastic Games, S. Subba Rao, R. Chandrasekaran, K.P. K. Nair Jul 1971

Algorithms For Discounted Stochastic Games, S. Subba Rao, R. Chandrasekaran, K.P. K. Nair

Research Reports from the Department of Operations

In this paper, a two person zero sum stochastic game with a finite state space is considered. The movement of the game from state to state is jointly controlled by the two players depending on their choice of strategies from a finite number of alternatives available to each player in each of the states. Considering an infinite number of transitions, Hoffman and Karp provided a convergent algorithm for the solution of this game when the future payoffs are not discounted. Subsequently, the authors presented a proof for a faster algorithm available in literature for solving the same problem. This paper …

Reduction Of Dimensionality In Dynamic Programming Of Higher Dimensions: A Comparative Study And Analysis Of Computational Aspects, Augustine O. Esogbue, Amar J. Singh Jul 1971

Reduction Of Dimensionality In Dynamic Programming Of Higher Dimensions: A Comparative Study And Analysis Of Computational Aspects, Augustine O. Esogbue, Amar J. Singh

Research Reports from the Department of Operations

One of the noble aims of dynamic programming at its conception -- namely, that of developing an operational method for the numerical solution of various control problems, is often thwarted for meaningfully scaled systems, by the curse of dimensionality. By far the most important contribution to modern dynamic programming is the development of efficient algorithms capable of being used, with present-day computational devices, to solve problems of a large-scale nature. Consequently, a number of algorithms have appeared in the literature in recent times, each geared towards ameliorating the above curse. The purpose of this paper is to present a didactic …

Quantitative Techniques For Research Program Planning In Structural Mechanics, Burton V. Dean Jun 1971

Quantitative Techniques For Research Program Planning In Structural Mechanics, Burton V. Dean

Research Reports from the Department of Operations

The Committee* has concluded that systematic procedures for research program formulation in structural mechanics have promise as methods for optimizing the allocation of research resources. Inasmuch as such procedures are not helpful in anticipating scientific breakthroughs, twenty-five per cent (25%) of the over-all research budget should be allocated, on the discretionary judgment of the Branch Staff Members, to fundamental research which has broad promise of application to Naval Missions. The matrix method is considered as the most promising planning technique. The Committee has recommended that a trial program be established within the Structural Mechanics Branch of the Office of Naval …

On The Uses Of Linear Regression Analysis In The Determination Of Continuous Utility Functions, Michael S. Salvador May 1971

On The Uses Of Linear Regression Analysis In The Determination Of Continuous Utility Functions, Michael S. Salvador

Research Reports from the Department of Operations

This paper investigates the characteristics of subjective estimation, specifically with regard to those techniques used in the measurement of utility as a function of some decision alternative. Regression analysis is applied to such bivariate estimates for the purpose of obtaining a generalized representation of the functional relationship expressed by same. Then, because of special properties of the subjective estimates themselves, certain statistics are shown to exist which simultaneously provide global measures of goodness of fit and consensus; furthermore, assuming the use of an iterative data collection process, there is also provided a measure of the rate of convergence of the …

Nonlinear Optimization With Upper And Lower Bounds, Vaughn E. Huckfeldt Apr 1971

Nonlinear Optimization With Upper And Lower Bounds, Vaughn E. Huckfeldt

Research Reports from the Department of Operations

Many nonlinear programming problems containing only upper and lower bounds are currently solved as unconstrained problems using transformation, or penalty methods of optimization. In this thesis it is shown that (1) Goldfarb's conjugate gradient algorithm can be simplified for NLP problems containing only upper and lower bounds, (2) the simplified algorithm requires less computer storage, and fewer multiplications per iteration with no loss in accuracy, and (3) the simplified algorithm is superior to transformation, or penalty methods when tested on published nonlinear test problems. A FORTRAN code for the nonlinear algorithm for upper and lower bounds, including complete documentation, is …

Integer Programming : Dual All-Integer Integer Programming (Gomory [2]), Harvey M. Salkin Apr 1971

Integer Programming : Dual All-Integer Integer Programming (Gomory [2]), Harvey M. Salkin

Research Reports from the Department of Operations

This work represents the sixth chapter of a forthcoming textbook “Integer Programming” to be written by Harvey M. Salkin. The cutting plane algorithm for the integer program presented in this chapter was developed by Ralph Gomory in 1960. Its similarity to the fractional method (Chapter 3) is principally due to the utilization of the (lexicographic) dual simplex method and the maintenance of (lexicographic) positive columns. The basic approach is, however, different from the fractional technique: there is no optimization, generating a constraint, reoptimization, etc. Rather, inequalities are generated at each iteration starting with the very first. Further, each of these …
