It is possible to extend the basic notion of "function call" to allow functions to have multiple return points. This turns out to be a surprisingly useful mechanism. Thi...
— In this paper we present a polynomial Navigation Function (NF) for a sphere world that can be constructed almost locally, with partial knowledge of the environment. The present...

In this paper we make use of a modified Grid Based Fuzzy System architecture, which may provide an exponential reduction in the number of rules needed. We also introduce an algori...
A common problem in applied mathematics is that of finding a function in a Hilbert space with prescribed best approximations from a finite number of closed vector subspaces. In ...
A minimum time problem with a nonlinear smooth dynamics and a target satisfying an internal sphere condition is considered. Under the assumption that the minimum time T be continu...
