Enum Constant Summary

Enum Constants

Enum Constant and Description
ENUM Find the next term in the enumeration of the target grammar.
QUERY Find a query over the given grammar.
REWRITE Find a pair of terms (t,s) in the target grammar which are equivalent but do not rewrite to the same term in the given rewriter (--sygus-rewrite=MODE).
REWRITE_INPUT Find a rewrite between pairs of terms (t,s) that are matchable with terms in the input assertions where t and s are equivalent but do not rewrite to the same term in the given rewriter (--sygus-rewrite=MODE).
REWRITE_UNSOUND Find a term t in the target grammar which rewrites to a term s that is not equivalent to it.

Enum Constant Detail

ENUM

public static final FindSynthTarget ENUM

Find the next term in the enumeration of the target grammar.

REWRITE

public static final FindSynthTarget REWRITE

Find a pair of terms (t,s) in the target grammar which are equivalent but do not rewrite to the same term in the given rewriter (--sygus-rewrite=MODE). If so, the equality (= t s) is returned by findSynth. This can be used to synthesize rewrite rules. Note if the rewriter is set to none (--sygus-rewrite=none), this indicates a possible rewrite when implementing a rewriter from scratch.

REWRITE_UNSOUND

public static final FindSynthTarget REWRITE_UNSOUND

Find a term t in the target grammar which rewrites to a term s that is not equivalent to it. If so, the equality (= t s) is returned by findSynth. This can be used to test the correctness of the given rewriter. Any returned rewrite indicates an unsoundness in the given rewriter.

REWRITE_INPUT

public static final FindSynthTarget REWRITE_INPUT

Find a rewrite between pairs of terms (t,s) that are matchable with terms in the input assertions where t and s are equivalent but do not rewrite to the same term in the given rewriter (--sygus-rewrite=MODE). This can be used to synthesize rewrite rules that apply to the current problem.

QUERY

public static final FindSynthTarget QUERY

Find a query over the given grammar. If the given grammar generates terms that are not Boolean, we consider equalities over terms from the given grammar. The algorithm for determining which queries to generate is configured by --sygus-query-gen=MODE. Queries that are internally solved can be filtered by the option --sygus-query-gen-filter-solved.

Method Detail

values

public static FindSynthTarget[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (FindSynthTarget c : FindSynthTarget.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static FindSynthTarget valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

fromInt

public static FindSynthTarget fromInt(int value)
                               throws CVC5ApiException

Throws:

CVC5ApiException

getValue

public int getValue()
