It implements then ISO core standard specification ISO 7.1.1.4 of witness variables. The predicate does not appear in the Novacore kernel. - Enhanced library(sequence): As an alternative we provide a new predicate firstof/2. The predicate is bootstraped from what is used in distinct/1, but makes use of free_variables/3 to determine the keys for deduplication during backtracking. Has more logical properties than distinct/2. - New library(plot): The library(plot) can generate line plots in the form of a SVG element. We currently provide the predicates plot/1 and plot/2 which take a list of points (x,y1,..,yn) and plot the lines (x,y1) ... (x,yn). The binary predicate allows specifying various plot options. Have Fun! Jan Burse, http://www.xlog.ch/ , 26.02.2025
