From b8301cde27c455c8da3e9017072a577a0816939b Mon Sep 17 00:00:00 2001 From: Andrew Reynolds Date: Fri, 21 Aug 2020 12:08:14 -0500 Subject: [PATCH] Connect the relevance manager to TheoryEngine and use it in non-linear arithmetic (#4930) This PR activates the use of the relevance manager in TheoryEngine and makes use of it (via Valuation) in the non-linear extension in arith. It removes a deprecated hack (addTautology) for doing this. This addresses CVC4/cvc4-projects#113. Note that the best method for relevance is interleaving, where roughly you gain on SMT-LIB: QF_NIA: +484-53 unsat +792-440 sat QF_NRA: +32-19 unsat +57-23 sat However, this PR does not (yet) enable this method by default. Note that more work is necessary to determine which lemmas require NEEDS_JUSTIFY, this PR identifies 2 cases of lemmas that need justification (skolemization and strings reductions). Regardless, the use of the relevance manager is limited to non-linear arithmetic for now, which is only able to answer "sat" when only arithmetic is present in assertions. --- src/options/arith_options.toml | 18 +++++++ src/options/theory_options.toml | 8 +++ src/smt/set_defaults.cpp | 16 ++++++ src/theory/arith/nl/nl_model.cpp | 52 +------------------ src/theory/arith/nl/nl_model.h | 18 ------- src/theory/arith/nl/nonlinear_extension.cpp | 50 ++++++++++++++++-- src/theory/arith/nl/nonlinear_extension.h | 10 +++- src/theory/output_channel.cpp | 8 +++ src/theory/output_channel.h | 6 ++- src/theory/quantifiers_engine.cpp | 3 +- src/theory/strings/inference_manager.cpp | 8 ++- src/theory/theory_engine.cpp | 41 +++++++++++++++ src/theory/theory_engine.h | 12 ++++- src/theory/valuation.cpp | 2 + src/theory/valuation.h | 8 ++- .../regress0/quantifiers/cegqi-nl-simp.cvc | 1 + test/regress/regress1/nl/issue3647.smt2 | 2 +- test/regress/regress1/nl/sin1-deq-sat.smt2 | 2 +- test/regress/regress1/nl/sin1-sat.smt2 | 2 +- test/regress/regress1/sygus/issue3648.smt2 | 2 +- 20 files changed, 183 insertions(+), 86 deletions(-) diff --git a/src/options/arith_options.toml b/src/options/arith_options.toml index 23ced4d8f..ab33f123c 100644 --- a/src/options/arith_options.toml +++ b/src/options/arith_options.toml @@ -533,6 +533,24 @@ header = "options/arith_options.h" read_only = true help = "whether to increment the precision for irrational function constraints" +[[option]] + name = "nlRlvMode" + category = "regular" + long = "nl-rlv=MODE" + type = "NlRlvMode" + default = "NONE" + help = "choose mode for using relevance of assertoins in non-linear arithmetic" + help_mode = "Modes for using relevance of assertoins in non-linear arithmetic." +[[option.mode.NONE]] + name = "none" + help = "Do not use relevance." +[[option.mode.INTERLEAVE]] + name = "interleave" + help = "Alternate rounds using relevance." +[[option.mode.ALWAYS]] + name = "always" + help = "Always use relevance." + [[option]] name = "brabTest" category = "regular" diff --git a/src/options/theory_options.toml b/src/options/theory_options.toml index 84c994c3f..6ec9d8854 100644 --- a/src/options/theory_options.toml +++ b/src/options/theory_options.toml @@ -34,3 +34,11 @@ header = "options/theory_options.h" default = "true" read_only = true help = "condense values for functions in models rather than explicitly representing them" + +[[option]] + name = "relevanceFilter" + category = "regular" + long = "relevance-filter" + type = "bool" + default = "false" + help = "enable analysis of relevance of asserted literals with respect to the input formula" diff --git a/src/smt/set_defaults.cpp b/src/smt/set_defaults.cpp index 5376d7418..7d2427015 100644 --- a/src/smt/set_defaults.cpp +++ b/src/smt/set_defaults.cpp @@ -1307,6 +1307,22 @@ void setDefaults(LogicInfo& logic, bool isInternalSubsolver) } } + if (logic.isTheoryEnabled(THEORY_ARITH) && !logic.isLinear() + && options::nlRlvMode() != options::NlRlvMode::NONE) + { + if (!options::relevanceFilter()) + { + if (options::relevanceFilter.wasSetByUser()) + { + Warning() << "SmtEngine: turning on relevance filtering to support " + "--nl-ext-rlv=" + << options::nlRlvMode() << std::endl; + } + // must use relevance filtering techniques + options::relevanceFilter.set(true); + } + } + // For now, these array theory optimizations do not support model-building if (options::produceModels() || options::produceAssignments() || options::checkModels()) diff --git a/src/theory/arith/nl/nl_model.cpp b/src/theory/arith/nl/nl_model.cpp index daa36f972..cc10d6659 100644 --- a/src/theory/arith/nl/nl_model.cpp +++ b/src/theory/arith/nl/nl_model.cpp @@ -16,6 +16,7 @@ #include "expr/node_algorithm.h" #include "options/arith_options.h" +#include "options/theory_options.h" #include "theory/arith/arith_msum.h" #include "theory/arith/arith_utilities.h" #include "theory/rewriter.h" @@ -279,11 +280,6 @@ bool NlModel::checkModel(const std::vector& assertions, std::vector check_assertions; for (const Node& a : assertions) { - // don't have to check tautological literals - if (d_tautology.find(a) != d_tautology.end()) - { - continue; - } if (d_check_model_solved.find(a) == d_check_model_solved.end()) { Node av = a; @@ -455,52 +451,6 @@ void NlModel::setUsedApproximate() { d_used_approx = true; } bool NlModel::usedApproximate() const { return d_used_approx; } -void NlModel::addTautology(Node n) -{ - // ensure rewritten - n = Rewriter::rewrite(n); - std::unordered_set visited; - std::vector visit; - TNode cur; - visit.push_back(n); - do - { - cur = visit.back(); - visit.pop_back(); - if (visited.find(cur) == visited.end()) - { - visited.insert(cur); - if (cur.getKind() == AND) - { - // children of AND are also implied - for (const Node& cn : cur) - { - visit.push_back(cn); - } - } - else - { - // is this an arithmetic literal?
