Getting started

Using LogicPalet one can easily edit logical formulas, build proofs, construct models (called GeoWorlds and DecaWorlds) and evaluate formulas in these models. LogicPalet can determine whether a formula is a consequence of given formulas, and can generate a GeoWorld satisfying given sentences.
These capabilities enable the automated grading of the online homeworks with clear computer generated feedback for the students.
