# BEAST 2 Help Me Choose Operator schedule --- transform

## Operator schedule – transform

This determine the transformation used when optimisation coercible parameters of operators. Let $c$ be the number of times the operator schedule selected an operator to optimise. The coercible parameters is updated with a weight proportional to $1/c$, if transform is none, $1/\log(c)$ if transform is log and $1/\sqrt(c)$ if transform is sqrt.

To guarantee auto optimisation stops changing the operators, sqrt and log should not be used (page 66-69, Fagundes De Carvalho, 2018).
