◆ rollback() [1/2]

template<class Evolver>
void rollback ( array_type & a,
Time from,
Time to,
Size steps )

solves the problem between the given times.

Warning
being this a rollback, from must be a later time than to.

◆ rollback() [2/2]

template<class Evolver>
void rollback ( array_type & a,
Time from,
Time to,
Size steps,
const condition_type & condition )

solves the problem between the given times, applying a condition at every step.

Warning
being this a rollback, from must be a later time than to.
