To program parallel systems efficiently and easily, a wide range of programming models
have been proposed, each with different choices concerning synchronization and …

We present the main concepts, components, and usage of G asol, a Gas AnalysiS and
Optimization tooL for Ethereum smart contracts. G asol offers a wide variety of cost models …

Analyzing Ethereum bytecode, rather than the source code from which it was generated, is a
necessity when:(1) the source code is not available (eg, the blockchain only stores the …

Gas is a measurement unit of the computational effort that it will take to execute every single
operation that takes part in the Ethereum blockchain platform. Each instruction executed by …

We present a comprehensive model of railway operations written in the active object
language ABS. The model is based on specifications taken from the rulebooks of Deutsche …

In cloud computing, software which does not flexibly adapt to deployment decisions either
wastes operational resources or requires reengineering, both of which may significantly …

Actor languages decouple communication from synchronization, which makes them suitable
for distributed and scalable applications with flexible synchronization patterns, but also …

Existing cost analysis frameworks have been defined for cumulative resources which keep
on increasing along the computation. Traditional cumulative resources are execution time …

Parameterized programs are composed of an arbitrary number of concurrent, infinite-state
threads. Automated safety and liveness proofs of such parameterized software are hard; …
