The Step to Rationality: The Efficacy of Thought Experiments in Science, Ethics, and Free Will
Examples from Archimedes, Galileo, Newton, Einstein, and others suggest that fundamental laws of physics were--or, at least, could have been--discovered by experiments performed n...

An Interior-Point Algorithm for Large-Scale Nonlinear Optimization with Inexact Step Computations
We present a line-search algorithm for large-scale continuous optimization. The algorithm is matrix-free in that it does not require the factorization of derivative matrices. Inste...

Logical Step-Indexed Logical Relations
We show how to reason about “step-indexed” logitions in an abstract way, avoiding the tedious, error-prone, and proof-obscuring step-index arithmetic that seems superficially...
