On a Combinatorial Problem
Let M be a set and F a family of its subsets. F is said by E. W. MILLER [5] to possess property B if there exists a subset K of M so that no set of the family F is contained either in K or in K (K is the complement of K in M) . HAJNAL and 1 [2] recently published a paper on the property B and its generalisations . One of the unsolved problems we state asks : What is the smallest integer in (n) ...
متن کاملThe Combinatorial Multi-Mode Resource Constrained Multi-Project Scheduling Problem
This paper presents the formulation and solution of the Combinatorial Multi-Mode Resource Constrained Multi-Project Scheduling Problem. The focus of the proposed method is not on finding a single optimal solution, instead on presenting multiple feasible solutions, with cost and duration information to the project manager. The motivation for developing such an approach is due in part to practica...

متن کاملA Combinatorial Problem with a Fibonacci Solution
For many years I have enjoyed lecturing to groups of high school students about the excitement of mathematics. One diversion that never failed to capture their attention was as follows: Everyone was asked to write down a three digit number (abc with a > c), reverse it (to form cba), find the difference (as a three-digit number) between the two numbers, and add the difference to its own reverse....
متن کاملLocal Search for a complex combinatorial problem
Iterated Local Search (ILS) is a popular metaheuristic search technique for use on combinatorial optimisation problems. As with most such techniques, there are many ways in which ILS can be implemented. The aim of this paper is to shed light on the best variants and choice of parameters when using ILS on a complex combinatorial problem with many objectives, by reporting on the results of an exh...
