<h3>Open topics</h3>
<p>
These is a selection of possible projects for master students that would like to work with us. We are also open for discussion about other topics.
Note that <strong>we have a few grants</strong> that can pay for most of the ideas presented in these projects.
If you are interested, just come and talk to us.

<div class="panel panel-default open-topic">
<h5><a href="content/projects/alloy-and-hl.html">Alloy and Hybrid Logic</a></h5>
<p>
The purpose of this project is to explore a variant of hybrid
logics in which worlds are equipped with Alloy models. In
principle, such a logic (generated via the hybridisation
method "hybridisation") provides a canonical language to address
reconfigurability in Alloy specifications.
</p>
<p>
The workplan involves the implementation of a calculus for this
logic (reported in <a href="http://www.sciencedirect.com/science/article/pii/S0167642316000691">Proof theory for hybridised logics</a>) and the
development of a case study that illustrates its
potentialities (and limitations) in the software development
process.
</p>
</div>
<div class="panel panel-default open-topic">
<h5><a href="content/projects/rg-in-alloy.html">Model checking R/G programs in Alloy</a></h5>
<p>When you run a program on your lap-top you "<emph>rely</emph>" on the operating system
not letting any other program to interfere with your state space. But programs
could be designed in a collaborative-style, with sub-programs helping each other
over a shared state. (Example: on-the-fly garbage collection.)
<!--
</p>
<p>Thus "no-interference" programming is just a special case of "allow-interference"
programming.
-->
In the early 1980s, Cliff Jones proposed a dynamic extension to
(static) Hoare logic: further to pre / post conditions, one could also specify interference
of the environment via <emph>rely / guarantee conditions</emph>. Interest on R/G programming is
growing a lot due to its potential for concurrency.
<!--
But it has become clear that
"allow-interference" programming has its subtleties, e.g. concerning
non-termination.
-->
</p>
<p>
In this project we would like to use <a href="http://alloy.mit.edu/alloy/">Alloy</a> to model the semantics of a simple
imperative language with R/G commands and model-check their interference.
The idea is to find design errors of (possibly non-terminating) R/G programs
by analysing finite traces only.
</p>
</div>
<div class="panel panel-default open-topic">
<h5><a href="content/projects/spec2proc.html">From specifications to concrete processes</a></h5>
<p>
This project aims at studying a <emph>dynamic logic with binders</emph>,
and (automatic) translations from specifications in (some fragment) of this logic into a concrete process algebra.
</p>
</div>
<div class="panel panel-default open-topic">
<h5><a href="content/projects/webreo.html">Reo families in your browser</a></h5>
<p>
This project aims at producing an extensible web-based framework to specify and analyse systems of coordinated components. It will involve developing a web-oriented framework for Reo connectors, possibly with a graphical frontend, and designing an extensible architecture with clear separations between the core model, the frontends, and the backends. To illustrate the extensibility of the framework, an extension for parameterised Reo connectors should be developed.
</p>
</div>
<div class="panel panel-default open-topic">
<h5><a href="content/projects/quantumpl.html">Quantum Programming Languages</a></h5>
<p>
This project aims at exploring the field of quantum programming languages and quantum artificial intelligence in a new line of research of the group of formal methods of Department of Informatics.
The project involves the implementation of some quantum algorithms and its comparison with more classical approaches.
</p>
</div>
<!--
<div class="panel panel-default open-topic">
<h5><a href="content/projects/tictacsensor.html">Tic-Tac Sensor</a></h5>
<p>
This project will exploit a recent extension to Wireless Sensor Networks (WSNs) under development at KUL, which include a cheap but powerful distributed clock provided by a new network infrastructure. You will be expected to investigate how to map an application specified in a synchronous dataflow language into:
(1) a set of deployment instructions, and (2) a set of rules for each node describing the local execution of the synchronous application.
</p>
</div>

<div class="panel panel-default open-topic">
<h5><a href="content/projects/making-logics-coalgebraic.pdf">[PhD] Making Logics Coalgebraic</a></h5>
<p>
The main goal of this PhD project is the development of a general notion of asymmetric combination of logic that turns logics coalgebraic. More concretely, a process that equips any given logic with suitable coalgebraic machinery re- spective to a given functor; this means that, in contrast to hybridisation, or temporalisation, the input parameter is not just the base logic, but also the functor that gives rise to the intended type of transitions.
