What is IPCO?
IPCO (Integer Programming and Combinatorial Optimization) is a conference that is sponsored
by the Mathematical Programming Society. IPCO is a forum for researchers and practitioners
working on various aspects of integer programming and combinatorial optimization. The aim is
to present recent developments in theory, computation, and applications of integer
programming and combinatorial optimization. There are two key features of the IPCO
conferences:
 First, there are no invited talks. Instead, a program committee selects the
contributions on the basis of extended abstracts submitted by prospective participants.
 Second, the papers at the meeting are presented in a single stream (no parallel sessions),
and preliminary versions of all papers are provided to participants at the beginning of the
meeting.
The presented papers are published in the proceedings of the conference. These proceedings
serve as a conference record as well as a means of rapid dissemination of results, since
they are published within six months of submission. Most journals, including Mathematical
Programming, Mathematics of Operations Research, INFORMS Journal on Computing, Operations
Research, SIAM Journal on Computing, SIAM Journal on Discrete Mathematics, SIAM Journal on
Optimization, Theoretical Computer Science do not view publication of an early version of a
paper in an IPCO proceedings as a prior publication which would otherwise make the paper unacceptable.
What is the Scope of IPCO?
The two themes of IPCO  integer programming and combinatorial optimization  are viewed in
a broad sense, to include algorithmic and structural results in topics such as
 approximation algorithms
 branch and bound algorithms
 branch and cut algorithms
 computational biology
 computational complexity
 computational geometry
 cutting plane algorithms
 diophantine equations
 geometry of numbers
 graph and network algorithms
 integer programming
 matroids and submodular functions
 online algorithms and competitive analysis
 polyhedral combinatorics
 randomized algorithms
 random graphs
 scheduling theory and scheduling algorithms
 semidefinite programs
In all these areas, IPCO welcomes structural and algorithmic results. IPCO is not
restricted to theory. Computational and practical work, implementations, novel applications
of these techniques to practical problems, and revealing computational studies, are most
welcome.
Which Type of Paper is Appropriate for IPCO?
The main acceptance criteria used by the program committee are the quality and originality
of the research, plus its interest to people working in the field. These acceptance criteria
have made it possible for younger, less established researchers to present their results in
an attractive format to a large audience of active researchers. The program committee
normally consists of researchers from a broad variety of fields. Therefore, someone
preparing an extended abstract can safely assume that a large portion of the program
committee will not be experts in the topic of the paper. These are precisely the readers to
whom the abstract should be directed. It also is crucial that the importance of the work is
understood by the committee. And of course, the claimed results should be correct and new.
The Timing of IPCO
IPCO is held every year, normally in late spring. Until 2018,
years divisible by three (ISMP years) were skipped. From 2021
on, IPCO does take place also in ISMP years, normally with a
considerable temporal and geographic distance. The submission
deadline usually is in the late fall of the year preceding the
meeting. All submissions are read by the program
committee. Approximately two months after the deadline, the
program committee meets and decides which papers to include in
the meeting. Authors are usually notified of the decision of
the program committee in the end of January. Authors of
accepted papers are asked to submit a final version (which may
again be an extended abstract or a full paper) by early
spring. These final versions are printed in the proceedings of
IPCO, which are provided to all participants at the
conference. Finally, the IPCO conference then takes place in
May or June. An IPCO conference usually takes three
days. During these three days, approximately thirtythree
papers are presented; each lecture is thirty minutes long.
