Homer: A Higher-Order Observational Equivalence Model checkER
We present HOMER, an observational-equivalence model checker for the 3rd-order fragment of Idealized Algol (IA) augmented with iteration. It works by first translating terms of the...

Observability index selection for robot calibration
— This paper relates 5 observability indexes for robot calibration to the “alphabet optimalities” from the experimental design literature. These 5 observability indexes are s...

Idealized Algol with Ground Recursion, and DPDA Equivalence
Abstract. We prove that observational equivalence of IA3 + Y0 (3rdorder Idealized Algol with 0th-order recursion) is equivalent to the DPDA Equivalence Problem, and hence decidable...

Process Equivalences as Global Bisimulations
: Bisimulation can be defined in a simple way using coinductive methods, and has rather pleasant properties. Ready similarity was proposed by Meyer et al. as a way to weakening the...
