tip
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 a "using [[smt_solver = ...]]" command if a proof is found by another SMT solver than the current one, to ensure it's also used for reconstruction
2010-12-15, by blanchet
make sure first-order occurrences of "False" and "True" are handled correctly -- this broke when adding proper support for higher-order occurrences
2010-12-15, by blanchet
consider "finite" overloaded in "precise_overloaded_args" mode
2010-12-15, by blanchet
added timeout max for remote server invocation
2010-12-15, by blanchet
fix translation of higher-order equality ("fequal") if "precise_overloaded_args" is "true"
2010-12-15, by blanchet
fix Vampire parsing problem
2010-12-15, by blanchet
improve partially tagged encoding by adding a helper fact that coalesces consecutive "ti" tags
2010-12-15, by blanchet
example tuning
2010-12-15, by blanchet
remove at most one double negation -- any other double negations are part of some higher-order reasoning and should be left alone, cf. "HO_Reas.thy"
2010-12-15, by blanchet
weaken the "expect" flag so that it doesn't trigger errors if a prover is not installed
2010-12-15, by blanchet
added example to exercise higher-order reasoning with Sledgehammer and Metis
2010-12-15, by blanchet
added Sledgehammer support for higher-order propositional reasoning
2010-12-15, by blanchet
add Metis support for higher-order propositional reasoning
2010-12-15, by blanchet
implemented partially-typed "tags" type encoding
2010-12-15, by blanchet
implemented "no_types" encoding, which is too unsound to be useful but can come in handy for evaluations
2010-12-15, by blanchet
implemented new type system encoding "overload_args", which is more lightweight than "const_args" (the unsound default) and hopefully almost as sound
2010-12-15, by blanchet
tuning: unused var
2010-12-15, by blanchet
added "type_sys" option to Sledgehammer
2010-12-15, by blanchet
merged
2010-12-15, by boehmes
updated SMT certificates
2010-12-15, by boehmes
fixed proof reconstruction for lambda-lifted problems (which broke when the lambda-lifting code was changed to operate on terms instead of on theorems)
2010-12-15, by boehmes
adapted the Z3 proof parser to recent changes in Z3's proof format;
2010-12-15, by boehmes
also show function definitions for higher-order free variables in Z3 models
2010-12-15, by boehmes
always add pair rules and function update rules automatically (Boogie provides pairs and function update as built-in concepts and does not generate background axioms for them)
2010-12-15, by boehmes
re-implemented eta-expansion, lambda-lifting, and explicit application on terms (exploiting the control over the term structure);
2010-12-15, by boehmes
re-ordered SMT normalization code (eta-normalization, lambda abstractions and partial functions will be dealt with on the term level);
2010-12-15, by boehmes
added option to enable trigger inference;
2010-12-15, by boehmes
moved SMT classes and dictionary functions to SMT_Utils
2010-12-15, by boehmes
tuned
2010-12-15, by boehmes
rewrite Z3 model equations one-by-one (the previous approach led to loss of information)
