Given a finite set $S$ of points (i.e. the stations of a radio network) on a $d$-dimensional Euclidean space and a positive integer $1\le h \le |S|-1$, the \minrangeh{d} problem consists of assigning transmission ranges to the stations so as to minimize the total power consumption, provided that the transmission ... more >>>

We address the problem of organizing a set $T$ of shared data into the memory modules of a Distributed Memory Machine (DMM) in order to minimize memory access conflicts (i.e. memory contention) during read operations. Previous solutions for this problem can be found as fundamental subprocedures of the PRAM simulation ... more >>>
