RHMC<br />
detM α =<br />
∫<br />
Dφ † Dφe −φ† r 2 (M)φ<br />
where r(x) = x −α/2 (rational approximation).<br />
RHMC is an exact algorithm, also allows larger δt than<br />
R algorithm ( δt ∼ 2/3m l ) so is faster (Kennedy/Clark<br />
claim 7 times better).<br />
MILC are now using the exact RHMC/RHMD algorithm<br />
for generating configurations (talk at ILDG11).<br />
