Representing reductions of NP-complete problems in logical frameworks: a case study
Under the widely believed conjecture P=NP, NP-complete problems cannot be solved exactly using efficient polynomial time algorithms. Furthermore, any instance of a NP-complete pro...

The smallest enclosing ball of balls: combinatorial structure and algorithms
We develop algorithms for computing the smallest enclosing ball of a set of n balls in d-dimensional space. Unlike previous methods, we explicitly address small cases (n ≤ d + 1...

Solving combinatorial exchanges: optimality via a few partial bids
We investigate the problem of matching buyers and sellers in a multi-item multi-unit combinatorial exchange so as to maximize either the surplus (revenue minus cost) or the tradin...

Implicit Program Synthesis by a Reversible Metainterpreter
Synthesis of logic programs is considered as a special instance of logic programming. We describe experience made within a logical metaprogramming environment whose central compone...

Scheduling in a Multi-Agent Environment
A new scheduling agent for existing CIM multi-agent system is being currently developed at the Technical University of Kosice. The basic idea is to create an agent based on Schedu...
