Description
We discuss the obvious generalization of the successful 'worm' simulation methods
from scalar field theories to abelian gauge models. Due to the geometrically
different situation, gauge simulations along these lines (so-far) still suffer
from critical slowing down. Other aspects like the low noise estimation
of observables -- here the Polyakov lines and partition function ratios --
do generalize. We exploit these to compare the 3D Z(2) gauge theory with effective string models.
