The problem of Scheduling $n$ Independent Jobs
on $m$ Unrelated Parallel Machines, when $m$
is fixed, is considered. The standard problem
of minimizing the makespan of the schedule
(SUM) and the bicriteria problem of scheduling
with bounded makespan and cost (SUMC), are
addressed, and randomized fully linear time
approximation schemes ... more >>>

In this paper we present some new results on the approximate parallel
construction of Huffman codes. Our algorithm achieves linear work
and logarithmic time, provided that the initial set of elements
is sorted. This is the first parallel algorithm for that problem
with the optimal time and ... more >>>

Implicit algorithms work on their input's characteristic functions and should solve problems heuristically by as few and as efficient functional operations as possible. Together with an appropriate data structure to represent the characteristic functions they yield heuristics which are successfully applied in numerous areas. It is known that implicit algorithms ... more >>>
