deadlock

Times this table was involved in a deadlock (cycle of threads waiting for each others table to complete)

wait

Times a thread waited for this table.

variables

The number of variables in the variant. The tabling logic adds a term ret(...) to the table for each answer, where each variable is an argument of the ret(...) term. The arguments are placed in depth-first lef-right order they appear in the variant. Optimal behaviour of the trie is achieved if the variance is as much as possible to the rightmost arguments. Poor allocation shows up as a low space_ratio statistics.

Below are some examples
