Abstract

The measure and conquer approach has proven to be a powerful tool
to analyse exact algorithms for combinatorial problems, like
Dominating Set and Independent Set. In this paper, we propose to
use measure and conquer also as a tool in the design of algorithms.
In an iterative process, we can obtain a series of branch and
reduce algorithms. A mathematical analysis of an algorithm in the
series with measure and conquer results in a quasiconvex
programming problem. The solution by computer to this problem not
only gives a bound on the running time, but also can give a new
reduction rule, thus giving a new, possibly faster algorithm. This
makes design by measure and conquer a form of computer aided
algorithm design.

When we apply the methodology to a Set Cover modelling of the
Dominating Set problem, we obtain the currently fastest known exact
algorithms for Dominating Set: an algorithm that uses $O(1.5134^n)$
time and polynomial space, and an algorithm that uses $O(1.5063^n)$
time.
