Random Polynomial-Time Attacks and Dolev-Yao Models
In this paper we present an extension of Dolev-Yao models for security protocols with a notion of random polynomial-time (Las Vegas) computability. First we notice that Dolev-Yao ...

Nondeterministic polynomial time factoring in the tile assembly model
Formalized study of self-assembly has led to the definition of the tile assembly model, Previously I presented ways to compute arithmetic functions, such as addition and multiplic...

A Polynomial Time Approximation Scheme for Minimum Routing Cost Spanning Trees
Given an undirected graph with nonnegative costs on the edges, the routing cost of any of its spanning trees is the sum over all pairs of vertices of the cost of the path between t...

The Non-Associative Lambek Calculus with Product in Polynomial Time
We prove, by introducing a new kind of sequent calculus, that the decision problem for the non-associative Lambek calculus with product belongs to PTIME. This solves an open prolem...
