Random $n$-ary sequence and mapping uniformly distributed

On $n$-ary Hypergroups and Fuzzy $n$-ary Homomorphism

Generating uniformly distributed random networks.

The analysis of real networks taken from the biological, social, and physical sciences often requires a carefully posed statistical null-hypothesis approach. One common method requires comparing real networks to an ensemble of random matrices that satisfy realistic constraints in which each different matrix member is equiprobable. We discuss existing methods for generating uniformly distributed...

Uniformly-Distributed Random Generation of Join Orders

In this paper we study the space of operator trees that can be used to answer a join query, with the goal of generating elements form this space at random. We solve the problem for queries with acyclic query graphs. We rst count, in O(n 3) time, the exact number of trees that can be used to evaluate a given query on n relations. The intermediate results of the counting procedure then serve to g...

Network Location Problem with Stochastic and Uniformly Distributed Demands

This paper investigates the network location problem for single-server facilities that are subject to congestion. In each network edge, customers are uniformly distributed along the edge and their requests for service are assumed to be generated according to a Poisson process. A number of facilities are to be selected from a number of candidate sites and a single server is located at each facil...
