摘要：We investigate the effectiveness of using smearing as a means to generate a preconditioning transformation
for gauge fields prior to fixing to Maximal Centre Gauge. This still leaves the gaugefixed
field in the original gauge orbit. As expected, we find that this preconditioning leads to
higher maxima of the gauge-fixing condition, resulting in lower numbers of P-vortices. We also
find that removing vortices appears to give a loss of confinement for all cases but that the string
tension as measured from vortex-only configurations drops from about 65% to as low as 26%
when using the preconditioning method.
