A MILP-based Approach to Path Sensitization of Embedded Software
José Carlos Campos Costa,
We propose a new methodology based on Mixed Integer Linear Programming
(MILP) for determining the input values that will exercise a specified
execution path in a program. In order to seamlessly handle variable
values, pointers and arrays, and variable aliasing, our method uses
memory addresses for variable references. This implies a dynamic
methodology where all decision are taken as the program executes. During
this execution, we gather constraints for the MILP problem, whose
solution will directly yield the input values for the desired path. We
present results that demonstrate the effectiveness of this approach. This
methodology was implemented into a fully functional tool that is capable
of handling medium sized real programs specified in the C language. Our
work is motivated by the complexity of validating embedded systems and
uses a similar approach to an existing HDL functional vector generation.
We are currently integrating this method with the mentioned hardware
method. The joint solution of the MILP problems will provide a
hardware/software co-validation tool.

Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
The program and more details are available here.
