Find changesets by keywords (author, files, the commit message), revision number or hash, or
revset expression
.
The revision graph only works with JavaScript-enabled browsers.
generate abs_eq, use it as a code equation for total quotients; no_abs_code renamed to no_code; added no_code for quotient_type command
2012-05-16, by kuncar
infrastructure that makes possible to prove that a relation is reflexive
2012-05-16, by kuncar
temporarily disable "ext" rule helpers until Metis supports them (and until they are properly evaluated)
2012-05-16, by blanchet
lower skolem penalty to ensure that some useful facts with existentials, e.g. congruence of "setsum", eventually get picked up
2012-05-16, by blanchet
treat sets specially in relevance filter, as they used to, to avoid cluttering the problem with facts about Set.member and Collect
2012-05-16, by blanchet
get ready for automatic generation of extensionality helpers
2012-05-16, by blanchet
minor slice tweaking (swapped two slices to move polymorphic encoding up a bit)
2012-05-16, by blanchet
more helpful error message
2012-05-16, by blanchet
transfer rules for many more list constants
2012-05-15, by huffman
made SML/NJ happy
2012-05-15, by blanchet
repair the Waldmeister endgame only for Waldmeister proofs
2012-05-15, by blanchet
fixed Waldmeister commutativity hack
2012-05-15, by blanchet
imported patch atp_tuning
2012-05-15, by blanchet
add transfer rules for nat_rec and funpow
2012-05-15, by huffman
add transfer rule for constant List.lists
2012-05-14, by huffman
add transfer rule for set_rel
2012-05-14, by huffman
ensure the "show" equation is not reoriented by Waldmeister
2012-05-14, by blanchet
ensure consistent naming of Waldmeister proof steps, so that they are not cleaned away by "clean_up_atp_proof_dependencies"
2012-05-14, by blanchet
repaired snag in debug function
2012-05-14, by blanchet
graceful handling of Waldmeister endgame
2012-05-14, by blanchet
improve parsing of Waldmeister dependencies (and kill obsolete hack)
2012-05-14, by blanchet
tuning
2012-05-14, by blanchet
added debugging function
2012-05-14, by blanchet
LEO-II's "--sos" option confusingly disables rather than enables SOS, and SOS seems to be ignored anyway; also, pass a number of facts that's more appropriate for each prover
2012-05-13, by blanchet
eta-reduce definition-like equations for THF provers; Satallax in particular seems to love that
2012-05-13, by blanchet
get rid of "conj_sym_kind" -- most interesting provers now have built-in sorts, and for the others (e.g. E) "Hypothesis" isn't too bad a default
2012-05-13, by blanchet
extend ATP data structure to avoid having to perform ((non-)capture avoiding) beta reduction -- fixes a bug in the THF translation of "is_measure.simps"
2012-05-13, by blanchet
reintroduced example now that it's no longer broken
2012-05-11, by blanchet
fixed "real" after they were redefined as a 'quotient_type'
2012-05-11, by blanchet
temporarily comment out broken nitpick example;
