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 $t-1$ .

Member Function Documentation

◆ clone()

ParametersStopCondition* bpp::ParametersStopCondition::clone ( ) const

inlinevirtual

Create a copy of this object and send a pointer to it.

Returns: A pointer toward the copy object.

Implements bpp::OptimizationStopCondition.
