Specification and Verification with the TLA+ Trifecta: TLC, Apalache, and TLAPS

Igor Konnov, Markus Kuppe, Stephan Merz

Using an algorithm due to Safra for distributed termination detection as a running example, we present the main tools for verifying specifications written in TLA+. Examining their…

Primal-Dual Method for Optimization Problems with Changing Constraints

Igor Konnov

We propose a modified primal-dual method for general convex optimization problems with changing constraints. We obtain properties of Lagrangian saddle points for these problems whi…

A Tendermint Light Client

Sean Braithwaite, Ethan Buchman, Ismail Khoffi +4

In Tendermint blockchains, the proof-of-stake mechanism and the underlying consensus algorithm entail a dynamic fault model that implies that the active validators (nodes that sign…

Exact Penalties for Decomposable Optimization Problems

Igor V. Konnov

We consider a general decomposable convex optimization problem. By using right-hand side allocation technique, it can be transformed into a collection of small dimensional optimiza…

Decentralized Multi-Agent Optimization Based on a Penalty Method

Igor Konnov

We propose a decentralized penalty method for general convex constrained multi-agent optimization problems. Each auxiliary penalized problem is solved approximately with a special…

Variational Inequality Type Formulations of General Market Equilibrium Problems with Local Information

Igor Konnov

We suggest a new approach to creation of general market equilibrium models involving economic agents with local and partial knowledge about the system and under different restricti…
