The terms occurring in an LK proof.
The name of eigenvariable that should be introduced in the decompositions.
Adds a decomposition (u,s), under the key s, to the delta table.
Adds a decomposition (u,s), under the key s, to the delta table. Specifically, s is the index and (u,T) is the key, where (u,S) is a decomposition of T. If the key already exists, (u,T) is appended the list of existing values
compute and print statistics about this delta-table
only include lines with at least k pairs (defaults to 1 which displays all lines)
A generalized delta table whose rows contains the results of Delta_G(...) instead of Delta(...).
A generalized delta table contains decompositions for subsets of a termset and one can extract grammars from it by simply iterating through its rows.
