Detailed Description

Stop condition on parameters.

This stops the optimization when $\forall i\; |\lambda_{i,t}-\lambda_{i,t-1}| \leq \mbox{tolerance}$, where $\lambda_{i, t}$ is the value of the ith parameter at iteration $t$, and $\lambda_{i, t-1}$ is the value of the ith parameter at iteration $t-1$.

◆ init()

◆ isToleranceReached()

bool ParametersStopCondition::isToleranceReached ( ) const
virtual

Tell if the we reached the desired tolerance with a given new set of estimates.

The new parameter list is compared to the last estimates, and the lastParameterEstimates list is actulaized with the newParameters list.

Returns
True if the tolerance level is reached.
