The Richardson-Lucy (R-L) algorithm has been widely used to restore degraded astronomical images. This algorithm is nothing more than the expectation-maximization (EM) algorithm applied to Poisson data. The R-L method is iterative in nature and converges to a (possibly local) maximum of the likeliho

Abstract
In the multifacility location problem, a number of new facilities are to be located so as to minimize a sum of weighted distances. Recently, a lower bound on the optimal value was developed, for use in deciding when to stop an iterative solution procedure. We develop a stronger bound that allows some computational savings.

The objective of this article was to find a location of a new facility on a network so that the total number (weight) of nodes within a prespecified distance R is minimized. This problem is applicable when locating an obnoxious facility such as garbage dumps, nuclear reactors, prisons, and military
## Abstract We consider an inverse problem for finding the anomaly of discontinuous electrical conductivity by one currentβvoltage observation. We develop a real time algorithm for determining the location of the anomaly. This new idea is based on the observation of the pattern of a simple weighted
We have been studying fuzzy control of the inverted double pendulum in computer simulations. We can control the inverted double pendulum by fuzzy control rules acquired by trial and error. In this research, we attempted to acquire fuzzy control knowledge for the double pendulum automatically by usin
