+abstract: "We present our work on a new modal logic of optimality, OPT, whose semantics are modeled in terms of optimal paths through reward-weighted transition systems. We prove some basic properties of OPT, including its status as a normal modal logic, as well as its relation to some of the standard modal axioms. We end with a discussion of applications to AI and future research directions and extensions."

+abstract: "We introduce VSPursuer, an automated reasoning tool that analyses matrices generated by Slaney’s MaGIC. The tool searches these matrices for a target logic to find one that witnesses the logic’s satisfaction of the Variable Sharing Property. We describe the theoretical background behind VSPursuer and highlight optimisations that enable our tool to determine whether a given matrix witnesses the property in polynomial time. We then give some example data sets for particular relevant logics, a theoretical analysis on the sizes of matrices generated by MaGIC which do not witness variable sharing, and close with an appendix explaining how to install and use VSPursuer."
