  The pseudoparticle approach is a numerical method to approximate path
integrals in SU(2) Yang-Mills theory. Path integrals are computed by summing
over all gauge field configurations, which can be represented by a linear
superposition of a small number of pseudoparticles with amplitudes and color
orientations as degrees of freedom. By comparing different pseudoparticle
ensembles we determine properties of confining gauge field configurations. Our
results indicate the importance of long range interactions between
pseudoparticles and of non trivial topological properties.
