Defined in:

Overview

weight_fcd 0..1 dynamic from current depth (uses max_depth) weight_fcd 0..1, :function dynamic fcd w/ function weight_fcd 0..1, 0..1 dynamic like previous but start and end of range mapped from codons weight_fcd 0..1, 0..1, :function like previous with function the function applies to the dynamic mapping of the current depth, and not the static mapping via codons of start and end which is always just linear weight_fcd { |max_depth| dynamic, expects a block which takes the ... max_depth and returns a proc which proc {|depth| ... } which takes the current depth }
