An Investigation Of Montmort's "Probleme De Recontres" And Generalizations, Ronald I. Greenberg Dec 1978

An Investigation Of Montmort's "Probleme De Recontres" And Generalizations, Ronald I. Greenberg

Computer Science: Faculty Publications and Other Works

I have investigated a problem which may be phrased in many ways, such as finding the probability of answering a given number of questions correctly on a randomly-completed matching test which may have a number of extra "dud" answers. I have determined such probabilities, the average number of correct answers, and other allied results. I have also investigated a related problem involving the number of ways of choosing a different element from each of a certain collection of sets.

Fuzziness And Catastrophe, Martin Zwick, Daniel Guy Schwartz, George G. Lendaris Nov 1978

Fuzziness And Catastrophe, Martin Zwick, Daniel Guy Schwartz, George G. Lendaris

Systems Science Faculty Publications and Presentations

In a recent short note, Flondor has alluded to a possible linkage of fuzzy set theory and catastrophe theory. We consider several features of catastrophe theory, namely the properties of discontinuous jumps, hysteresis, and divergence in the "cusp catastrophe," and the role of the bias factor in the "butterfly catastrophe," which have affinities to and suggest possible extensions of fuzzy set ideas. Certain functions extensively considered in catastrophe theory lend themselves in some cases to interpretation as membership functions. The use of such functions may be of interest for the characterization of linguistic descriptions which are time-varying and encompass both …


Requisite Variety And The Second Law, Martin Zwick Nov 1978

Requisite Variety And The Second Law, Martin Zwick

Systems Science Faculty Publications and Presentations

Although the Law of Requisite Variety (LRV) speaks directly about entropy (of a set of disturbances to a system, and of the states and effects of a regulator), the relation of Ashby's principle to the Second Law of Thermodynamics does not appear to have been commented on, In this paper, it is shown that, when regulation is viewed as a temporal process, the LRV can be interpreted as a statement of, and, in fact, a consequence of, the Second Law. In essence, the regulator reduces the variety (entropy) of the system being regulated by a compensatory increase of variety (entropy) …

A Rapid Algorithm For Reliability Optimization Of Parallel Redundant Systems, Arcot Desai Narasimhalu, H. Sivaramakrishnan Oct 1978

A Rapid Algorithm For Reliability Optimization Of Parallel Redundant Systems, Arcot Desai Narasimhalu, H. Sivaramakrishnan

Research Collection School Of Computing and Information Systems

A rapid method is proposed for optimization of reliability of multiconstraint parallel redundant systems. The constraints need not be linear. This method provides good starting values, which are close to the boundary of the feasible region, for the number of redundant units in each subsystem. No proof has been presented to establish the optimality obtained by this method. Yet for examples tried out this method provides optimal or near optimal solutions.

On List Structures And Their Use In The Programming Of Unification, F. Lockwood Morris Aug 1978

On List Structures And Their Use In The Programming Of Unification, F. Lockwood Morris

Electrical Engineering and Computer Science - Technical Reports

The notion of list structure is discussed, and a new construct is introduced into LISP which permits the computation of list structures containing cycles without recourse to operations which alter existing structures. It is shown that list structures can be used to represent both finite and “rational” infinite terms. Substitutions (generalized for a term algebra which includes infinite terms) are discussed, “tables” are introduced as an abstract data type, and two methods of representing substitutions by tables, together with their interrelation, are considered. Concise programs are given for a succession of forms of Robinson’s unification algorithm, including one which operates …
