The *bound* keyword turns on min/max bounds for bias coefficients Cij

for all bonds.  Cij is a prefactor for each bond on the bias potential

of maximum strength Vmax.  Depending on the choice of *alpha* and

*Btarget* and *Vmax*\ , the booststatting can cause individual Cij

*Btarget* and *Vmax*\ , the boostostatting can cause individual Cij

values to fluctuate.  If the fluctuations are too large Cij\*Vmax can

exceed low barrier heights and induce bad event dynamics.  Bounding

the Cij values is a way to prevent this.  If *Bfrac* is set to -1 or

A setting of 0 means *Vmax* is adjusted every time an event occurs and

bond pairs are recalculated.  A setting of N > 0 timesteps means

*Vmax* is adjusted on the first time an event occurs on a timestep >=

N steps after the previous adjustment.  The adjustement to *Vmax* is

N steps after the previous adjustment.  The adjustment to *Vmax* is

computed as follows.  The current average of all Cij\*Vmax values is

computed and the *Vmax* is reset to that value.  All Cij values are

changed to new prefactors such the new Cij\*Vmax is the same as it was

For value 10, each bond instantaneous boost factor is given by the

equation for Bij above.  The total system boost (average across all

bonds) fluctuates, but should average to a value close to the

For value 12, the numerator is a count of all biased bonds on each
