Truncate
(proportion=0.2)[source]¶ Truncate exploit strategy: if the selected candidate job is in the worst n%, use a candidate job in the top n% instead.
Parameters: proportion (float) – Proportion of jobs that are considered to be “best” jobs, and “worst” jobs. For example, if proportion = 0.2
, if the selected candidate job is in the bottom 20%, it will be replaced by a job in the top 20%. Must satisfy0 < proportion <= 0.5
