Model Checking Navigation

CS 290C: Formal Models for Web Software Lecture 4: Model Checking Navigation Models with Spin Instructor: Tevfik Bultan. Model Checking Navigation. We discussed modeling navigation using state machines. Once we have a navigation model, we would like to analyze it.

SPIN

SPIN. An explicit state model checker. Properties. Safety properties Something bad never happens Properties of states Liveness properties Something good eventually happens Properties of paths. Reachability is sufficient. We need something more complex to check liveness properties.
