Parallel solving (#7814)
* very basic setup

* ensure solve_eqs is fully disabled when smt.solve_eqs=false, #7743

Signed-off-by: Nikolaj Bjorner <nbjorner@microsoft.com>

* respect smt configuration parameter in elim_unconstrained simplifier

Signed-off-by: Nikolaj Bjorner <nbjorner@microsoft.com>

* indentation

* add bash files for test runs

* add option to selectively disable variable solving for only ground expressions

Signed-off-by: Nikolaj Bjorner <nbjorner@microsoft.com>

* remove verbose output

Signed-off-by: Nikolaj Bjorner <nbjorner@microsoft.com>

* fix #7745

axioms for len(substr(...)) escaped due to nested rewriting

* ensure atomic constraints are processed by arithmetic solver

* #7739 optimization

add simplification rule for at(x, offset) = ""

Introducing j just postpones some rewrites that prevent useful simplifications. Z3 already uses common sub-expressions.
The example highlights some opportunities for simplification, noteworthy at(..) = "".
The example is solved in both versions after adding this simplification.

* fix unsound len(substr) axiom

Signed-off-by: Nikolaj Bjorner <nbjorner@microsoft.com>

* FreshConst is_sort (#7748)

* #7750

add pre-processing simplification

* Add parameter validation for selected API functions

* updates to ac-plugin

fix incrementality bugs by allowing destructive updates during saturation at the cost of redoing saturation after a pop.

* enable passive, add check for bloom up-to-date

* add top-k fixed-sized min-heap priority queue for top scoring literals

* set up worker thread batch manager for multithreaded batch cubes paradigm, need to debug as I am getting segfault still

* fix bug in parallel solving batch setup

* fix bug

* allow for internalize implies

* disable pre-processing during cubing

* debugging

* remove default constructor

* remove a bunch of string copies

* Update euf_ac_plugin.cpp

include reduction rules in forward simplification

* Update euf_completion.cpp

try out restricting scope of equalities added by instantation

* Update smt_parallel.cpp

Drop non-relevant units from shared structures.

* process cubes as lists of individual lits

* merge

* Add support for Algebraic Datatypes in JavaScript/TypeScript bindings (#7734)

* Initial plan

* Add datatype type definitions to types.ts (work in progress)

* add option to control epsilon #7791

#7791 reports on using model values during lex optimization that break soft constraints.
This is an artifact of using optimization where optimal values can be arbitrarily close to a rational.
In a way it is by design, but we give the user now an option to control the starting point for epsilon when converting infinitesimals into rationals.

* add option to control epsilon #7791

#7791 reports on using model values during lex optimization that break soft constraints.
This is an artifact of using optimization where optimal values can be arbitrarily close to a rational.
In a way it is by design, but we give the user now an option to control the starting point for epsilon when converting infinitesimals into rationals.

* chipping away at the new code structure

* comments

* debug infinite recursion and split cubes on existing split atoms that aren't in the cube

* share lemmas, learn from unsat core, try to debug a couple of things, there was a subtle bug that i have a hard time repro'ing

* merge

* resolve bad bug about l2g and g2l translators using wrong global context. add some debug prints

* initial attempt at dynamically switching from greedy to frugal splitting strategy in return_cubes. need to test. also there is some bug where the threads take forever to cancel?

Parallel solving (#7759)

* respect smt configuration parameter in elim_unconstrained simplifier

Signed-off-by: Nikolaj Bjorner <nbjorner@microsoft.com>

* indentation

* add bash files for test runs

* add option to selectively disable variable solving for only ground expressions

Signed-off-by: Nikolaj Bjorner <nbjorner@microsoft.com>

* remove verbose output

Signed-off-by: Nikolaj Bjorner <nbjorner@microsoft.com>

* fix #7745

axioms for len(substr(...)) escaped due to nested rewriting

* ensure atomic constraints are processed by arithmetic solver

* #7739 optimization

add simplification rule for at(x, offset) = ""

Introducing j just postpones some rewrites that prevent useful simplifications. Z3 already uses common sub-expressions.
The example highlights some opportunities for simplification, noteworthy at(..) = "".
The example is solved in both versions after adding this simplification.

* fix unsound len(substr) axiom

Signed-off-by: Nikolaj Bjorner <nbjorner@microsoft.com>

* FreshConst is_sort (#7748)

* #7750

add pre-processing simplification

* Add parameter validation for selected API functions

* updates to ac-plugin

fix incrementality bugs by allowing destructive updates during saturation at the cost of redoing saturation after a pop.

* enable passive, add check for bloom up-to-date

* add top-k fixed-sized min-heap priority queue for top scoring literals

* set up worker thread batch manager for multithreaded batch cubes paradigm, need to debug as I am getting segfault still

* fix bug in parallel solving batch setup

* fix bug

* allow for internalize implies

* disable pre-processing during cubing

* debugging

* remove default constructor

* remove a bunch of string copies

* Update euf_ac_plugin.cpp

include reduction rules in forward simplification

* Update euf_completion.cpp

try out restricting scope of equalities added by instantation

* Update smt_parallel.cpp

Drop non-relevant units from shared structures.

* process cubes as lists of individual lits

* merge

* Add support for Algebraic Datatypes in JavaScript/TypeScript bindings (#7734)

* Initial plan

* Add datatype type definitions to types.ts (work in progress)
