Ant colony optimization (ACO) has become one of the
popular metaheuristics used for tackling optimisation
problems. Its popularity grows steadily, and the area
of applications constantly widens. Recent research
shows that ACO is competitive and applicable to
various real-world optimisation problems. ACO has
been initially developed to handle only the discrete
optimisation problems. In this work, we present a way
to extend ACO, so that it can also be applied to both
continuous and mixed-variable optimisation problems.
We initially focus only on the continuous case.
