What is it about?
Rare events in atomistic simulations are difficult to simulate straightforwardly (e.g. by Molecular Dynamics), as they are by definition rare and may thus take a long time to happen (sometimes longer than you can afford to simulate for). The titular kinetic activation-relaxation technique (k-ART) makes this possisble by ignoring all uninteresting movements of atoms before they actually make a rare event, which may allow much longer simulated times.

Why is it important?
Our program k-ART is an implementation of the Kinetic Monte Carlo method, where a system progresses through a series of events, the rates of which depend on the barriers that separate initial and final states of each event. The advantage of k-ART is that operates off-lattice and can thus be employed even for very complex systems.
