Tue, 17 Mar 2009 13:33:21 +0100 wenzelm goal_tac: finish marked assumptions from left to right -- corresponds better with the strategy of etac, with significant performance gains in some situations; changeset | files
Tue, 17 Mar 2009 12:10:42 +0100 wenzelm eq_assumption: slightly more efficient by checking (open) result of Logic.assum_problems directly; changeset | files
Tue, 17 Mar 2009 12:09:43 +0100 wenzelm tuned aeconv: test plain aconv before expensive eta_contract; changeset | files
Mon, 16 Mar 2009 23:52:30 +0100 wenzelm substantial speedup of assumption and elim-resolution: Logic.assum_problems refrains from eager application of parameters, discriminate via Term.could_unify before invoking full unification (assumes terms in beta-normal form, as do higher term net operations anyway); changeset | files
Mon, 16 Mar 2009 23:39:44 +0100 wenzelm refined is_norm_hhf: reject beta-redexes (rules based on term nets or could_unify assume normal form), also potentially faster by avoiding expensive Envir.beta_eta_contract; changeset | files
Mon, 16 Mar 2009 23:36:55 +0100 wenzelm provide Simplifier.norm_hhf(_protect) as regular simplifier operation; changeset | files
Mon, 16 Mar 2009 19:40:03 +0100 wenzelm method parser: pass proper context; changeset | files
Mon, 16 Mar 2009 18:24:39 +0100 wenzelm merged changeset | files
