MINION is used as the constraint solver implementing constraint satisfaction to generate distinguishing test cases.

The computeDistinguishingTest algorithm calls the MINION constraint solver to find solutions.

Constraint-based test data generation uses MINION as the underlying constraint solver.

Finite Domain uses → 93% 2e

MINION operates over finite domains for all integer variables in the constraint system.

The MINION-based approach was developed and applied by researchers at Technische Universität Graz.

Variable Ordering uses → 93% 1e

Variable ordering is imposed in MINION to improve its search performance for constraint solving.

CBMC ← compares with 90% 1e

CBMC is compared with MINION as an alternative tool for generating distinguishing test cases, differing in its use of SAT-solving.

Z3 SMT solver compares with → 87% 1e

Z3 SMT-solver was used by the same research group for contract mutation, in contrast to MINION used for program-level distinguishing test cases.
