Abstract

Using dynamical algebraic multi-grid (DAMG) we simulated scalar fields on fixed random triangulated grids. We measured the auto-correlation time τ of 〈(x - 〈x〉)²〉 for runs on a 10 000 triangles grid. We compared the DAMG value (τ ∼ 2.5), with the one-level relaxations (τ ∼ 1500). Then, we estimated the dynamical critical exponent z. The usual heat-bath algorithm displays critical slowing down (CSD) with ζ ≉ 1.5 while for DAMG ζ ≉ 0.
