Your future career
Further studies in a PhD in mathematics or computer science.
Jobs in R&D in areas at the interface of mathematics and computer science, typically optimization and machine learning. Machine learning courses, in particular, are professionalized so that graduates, right at graduation, have operational skills much in demand in the industry.
Professional integration
Continuing in a PhD in mathematics or computer science. Jobs in R&D in areas between mathematics and computer science, typically optimization and machine learning. Machine learning courses, in particular, are made to be usable directly in the industry.
Study objectives
At the end of the master, the student should be able to continue with a PhD in mathematics or computer science, with a large knowledge of areas at the interface of both fields. Some courses, such as optimization and machine learning, are also especially designed to be directly usable in the industry.
Major thematics of study
Mathematics and computer science: discrete and continuous optimization, algorithms and combinatorics, geometry, data science, large random matrices, random graphs.
Study organization
Une première période de « socle » de 4 semaines pour faire une remise à niveau en mathématiques et en informatique. Suivi d’un tronc commun de 10 semaines avec 3 UE composée chacune de deux cours. Une seconde période avec deux options de spécialisation à choisir parmi quatre propositions. Un stage de recherche ou en entreprise de 4 mois minimum.

Major thematics of Research
This speciality of M2 was created as a natural continuation of the successful Labex Bezout. It therefore benefits from a stimulating research environment, developed by the three excellent laboratories in mathematics and computer science of the « cité Descartes »: CERMICS, LAMA and LIGM.

| Discrete and continuous optimization Discrete optimization : Min-max results in combinatorial optimization provide elegant mathematical statements, are often related to the existence of efficient algorithms, and illustrate well the power of duality in optimization. The course will rely on concrete examples taken from industry. Plan of the course: Discrete optimization in bipartite graphs. Chains and antichains in posets. Chordal graphs. Perfect graphs. Lovász theta function. Continuous optimization : The course will cover over theoretic and algorithmic aspects of convex optimization in a finite-dimensional setting.

Weak and strong duality, Farkas Lemma. Sparse solutions via L1 penalization. LASSO method. Langue de l'enseignementANGLAIS / ENGLISH | 6 | 20h | 30h | |
| Probabilistic algorithms and combinatorics Probabilistic algorithms. This course is about randomized algorithms, which relies on randomness to speed up their running time. The methods: Las Vegas and Monte Carlo algorithmes, complexity classes for randomized algorithms, lower bounds: Yao’s Minimax principle, some probabilistic settings useful in algorithms: coupon collector, birthday problem, …Applications: analysis of Quicksort and Quickselect algorithms, stable marriage problem, probabilistic data structures (hash tables, skip lists, treaps, …), probabilistic counting, graph algorithms. Combinatorics. The lectures on enumerative combinatorics will consist in the study of classical objects: permutations, trees, partitions, parking functions, …- classical sequences: factorial, Catalan, Schroder, …- classical methods: bijections, group actions, induction, generating series.The lectures will be heavily based on the study of various examples, some very easy and others trickier.

| Algebraic combinatorics and formal calculus Operads in combinatorics: Informally, an operad is a space of operations having one output and several inputs that can be composed. We present some elementary objects of algebraic combinatorics: combinatorial classes and algebras. We introduce (non-symmetric) operads and study some tools allowing to establish presentations by generators and relations of operads. Koszul duality and generalizations: colored operads, symmetric operads, and pros. We shall also explain how the theory of operads offers a tool to obtain enumerative results. Algebraic combinatorics : study of classical symmetric functions and discussion about representation theory, noncommutative symmetric functions (NCSF), the definition of Hopf algebras, the dual algebra of NCSF, quasi-symmetric functions, the modern generalizations of those algebras and use of all these algebraic properties (transition matrices, expressions in various bases, morphisms of Hopf algebras) to solve (classical) combinatorial questions.
