X-Git-Tag: cvc5-1.0.0~6914 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0b2f9943d55152e0958369083649dd71340864c9;p=cvc5.git More preparation for CASC proofs. Minor fix for sort inference (rewrite new assertions). Bug fix for ambqi : simplify correctly for multi-sorted case. Bug fix for fmc : only do exh-simplification for uninterpreted sorts, ensure reps are enumerated for quantification over Real. --- diff --git a/contrib/run-script-cascj7-fnt b/contrib/run-script-cascj7-fnt index 11133cd0f..5d51381da 100755 --- a/contrib/run-script-cascj7-fnt +++ b/contrib/run-script-cascj7-fnt @@ -25,8 +25,8 @@ function trywith { if [ ${PIPESTATUS[1]} -eq 0 ]; then exit 0; fi } -trywith 30 --finite-model-find -trywith 30 --finite-model-find --mbqi=gen-ev --uf-ss-totality --decision=internal -trywith 10 --finite-model-find --disable-uf-ss-min-model -trywith $to --finite-model-find --mbqi=abs --pre-skolem-quant +trywith 30 --finite-model-find --sort-inference --uf-ss-fair +trywith 30 --finite-model-find --mbqi=gen-ev --uf-ss-totality --decision=internal --sort-inference --uf-ss-fair +trywith 10 --finite-model-find --disable-uf-ss-min-model --sort-inference --uf-ss-fair +trywith $to --finite-model-find --mbqi=abs --pre-skolem-quant --sort-inference --uf-ss-fair echo "% SZS status" "GaveUp for $filename" diff --git a/contrib/run-script-cascj7-fof b/contrib/run-script-cascj7-fof index 151413ac2..eb0478e24 100755 --- a/contrib/run-script-cascj7-fof +++ b/contrib/run-script-cascj7-fof @@ -7,8 +7,6 @@ let "to = $2 - 85" file=${bench##*/} filename=${file%.*} -echo "Run $bench at $2" - # use: trywith [params..] # to attempt a run.
