New Path Order for Exponential Time In this talk I present the Exponential Path Order EPO*, a product of joint work with Naohi Eguchi during my stay at JAIST. Inspired by a novel term rewriting characterisation of the exponential time functions FEXP, this order is carefully trimmed so that compatibility of TRSs implies exponentially bounded runtime complexity. Moreover, the order is complete in the sense that every exponential time function can be expressed by a TRS compatible with an instance of EPO*.
