The LIRMM (UMR 5506, University of Montpellier, CNRS) is
recruiting a
full-time research engineer for a period of 12 months in the field
of
automated proof. The desired start date is January 1, 2023, and
the
position will be located in Montpellier (France).</p>

<span style="font-weight: normal">The purpose of this position is
to
strengthen the software development capabilities of the MaREL
team
(specialized in the field of software engineering) of the
Computer
Science department of LIRMM. The person hired will be involved
in the
development of Goéland, an automated reasoning tool developed in
the
team by Julie Cailler (PhD student) for over a year. This tool
is
based upon a new proof search procedure for first-order logic,
which
leverages concurrency to produce proofs in the context of the
tableaux method. This tool currently gives excellent results (as
measured by the number of solved problems) in comparison with
similar
tools. Notably, it achieves better results in some problem
categories
than similar (tableaux-based) tools, some of which have been
established for years. A conference article on Goéland has been
accepted for publication at IJCAR 2022, a rank A conference,
demonstrating the interest of the community for the approach
used by
that tool. Furthermore, Goéland has taken part in the CASC-J11
competition, organized in parallel with IJCAR 2022, and in which
the
current best automated deduction tools compete on different sets
of
problems. The tool has been awarded the “best newcomer”
distinction during this competition.</span></p>
<p class="western" style="margin-bottom: 0cm; line-height: 100%"
align="justify">
<span style="font-weight: normal">The hired person will
participate
in the development and maintenance of the Goéland software,
which is
developed using Go, a language suited to concurrent programming.
The
aim of this position is twofold. The first mission is to get the
tool
in working for competitions, particularly CASC, a yearly
occurrence
that serves as a display of our work. The second is to apply the
tool
in a more industrial setting. A benchmark of problems
originating
from the modeling of industrial applications with the B method
is
already available (as a result of the ANR project Bware) but a
number
of extensions to Goéland are needed before it can be used on
this
benchmark.</span></p>
<p class="western" style="margin-bottom: 0cm; line-height: 100%"
align="justify">
<span style="font-weight: normal">In more detail, the assignments
of
the hired person will include:</span></p>
<ul>
<li>
<p class="western" style="margin-bottom: 0cm; line-height: 100%"
align="justify"> <span style="font-weight: normal">Improving
tests for proof search with equality. Equality reasoning is

<li>
<p class="western" style="margin-bottom: 0cm; line-height: 100%"
align="justify"> <span style="font-weight: normal">Integrating
polymorphism in the proof search. Proof search with
polymorphic types has been developed recently, but this
feature has yet to be integrated and also requires tests for
validation.</span></p>

<li>
<p class="western" style="margin-bottom: 0cm; line-height: 100%"
