The Sharpest Cut is written in honor of Manfred Padberg, who has made
fundamental contributions to both the theoretical and computational sides of
integer programming and combinatorial optimization. This outstanding
collection presents recent results in these areas that are closely connected
to Padberg's research. His deep commitment to the geometrical approach to
combinatorial optimization can be felt throughout this volume; his search
for increasingly better and computationally efficient cutting planes gave
rise to its title.
The peer-reviewed papers contained here are based on invited lectures given
at a workshop held in October 2001 to celebrate Padberg's 60th birthday.
Grouped by topic (packing, stable sets, and perfect graphs; polyhedral
combinatorics; general polytopes; semidefinite programming; computation),
many of the papers set out to solve challenges set forth in Padberg's work.
The book also shows how Padberg's ideas on cutting planes have influenced
modern commercial optimization software. In addition, the volume contains a
short curriculum vitae, a personal account of Padberg's work by Laurence
Wolsey, and an appendix with reflections from Egon Balas, Claude Berge, and

This is to inform you that I am organizing the session on iterative
methods at the 17th IMACS world congress in Paris, July 11-15, 2005.
This sequence of sessions at IMACS world congresses had been
initiated by Willi Schoenauer and Ruediger Weiss and I am glad to

Martin Gutknecht had first planned to organize it but was forced to
cancel this project because of an unfortunate conflict of dates with
the SIAM meeting.
According to the wishes of Willi, the present edition is intended to
be a forum for young researchers with new ideas and we therefore
address the reputed researchers to send their best students or
transmit them their invitation so that they can present their ideas
On practical grounds, contributors should email me, if possible

mathematicians and researchers to present, discuss and exchange ideas,
results, work in progress and experiences in the area of parallel and
distributed computing for problems in science and engineering
applications and inter-disciplinary applications.
Among the main topics (but not limited to) are:
1. development of advanced parallel and distributed methods,
2. parallel and distributed computing techniques and codes,
3. practical experiences using various parallel and distributed systems
with software such as MPI, PVM, and HPFortran, OpenMP, etc.
4. domain decomposition,
5. loop and task parallelism,

Title: Optimization problems in inversion of stratigraphic models
In oil exploration, stratigraphic modelling is used to validate
geological interpretations, to estimate the location of reservoirs
or to quantify petrophysic properties of rocks.
A stratigraphic model describes the time evolution of the topographic
surface of a sedimentary basin and of its sedimentary filling.
Based on a forward modelling approach, it simulates the average
geometry of sedimentary units and characterizes their sedimentary
facies (depositional water depth, sand/shale ratio).
One of the main difficulties in using such forward models is
that their input parameters (mainly accomodation, sedimentary input
at its boundaries, sediment transport parameters) have to be inverted
to fit seismic and well log data. Interpretation of seismic data and
well logs provide depth of sedimentary deposit surfaces, ranges of
bathymetry under which sediments have been deposited and
The inverse problem of stratigraphic models consists in the determination
of the model parameters that best match those interpreted data.
The main difficulties lie in the non-linearity of the model with respect
to the parameters, in the various nature of the different
parameters and data, and in the uncertainties we have on these data.
This inverse problem is classicaly formulated as a minimization problem
where a cost function measures the mismatch between model responses
and data. A priori information is introduced by means of additionnal
penalization terms and/or constraints (mainly non-linear constraints).
The subject of the postdoc focuses on how to solve this inverse problem :
In a first step, the candidate will develop and/or adapt existing
optimization methods to this kind of problem. For linear constraints,
a Sequential Quadratic Programming approach in which the QP's are solved
by an augmented Lagrangian method has been developed and has proven
to be very efficient on other applications in geosciences. An extension
of this approach to non-linear constraints is required.
In a second step, the candidate will test the approach on a real dataset
from an existing sedimentary basin. He will focus on the sensitivity of the
inverted model to the set of constraints given by the geological interpretation.
Education and qualification:
With an interest and motivation for nonlinear optimization and convex analysis
applied to geosciences, the candidate has a PhD in applied mathematics.
Good knowledge in C and/or Fortran is required.
Ideally, the candidate is a non-french citizen with good working
knowledge of the English language.
Institut Francais du Petrole (IFP, http://www.ifp.fr) is situated at
about 10 kilometers from Paris and offer excellent working conditions
in a lively research environment.
Duration: 1 year.
Salary: ~1900 euros (taxes excluded).
