A graph G is perfect if for every induced subgraph H, the chromatic number of H equals the size of the largest complete subgraph of H, and G is Berge if no induced subgraph of G is an odd cycle of length at least five or the complement of one. The ?strong perfect graph conjecture? (Berge, 1961) asserts that a graph is perfect if and only if it is Berge. A stronger conjecture was made recently by Conforti, Cornu?ejols and Vuiskovi?c ? that every Berge graph either falls into one of a few basic… 
Progress on perfect graphs
TLDR
The main aspects of perfect graphs and their relevance are surveyed and the recent proof of the Strong Perfect Graph Conjecture of Berge from 1961 is outlined.
Odd Pairs of Cliques
A graph is Berge if it has no induced odd cycle on at least 5 vertices and no complement of induced odd cycle on at least 5 vertices. A graph is perfect if the chromatic number equals the maximum
The perfection and recognition of bull-reducible Berge graphs
TLDR
This paper gives a simple proof that every bull-reducible Berge graph is perfect and leads to a recognition algorithm for this new class of perfect graphs whose complexity, O(n 6 ) , is much lower than that announced for perfect graphs.
Forbidden Induced Subgraphs of Double-split Graphs
TLDR
This work finds the forbidden induced subgraph characterization of doubled graphs; it contains 44 graphs and is the first of its kind.
Sum-perfect graphs
Towards a constructive formalization of Perfect Graph Theorems
TLDR
This paper model finite simple graphs in the constructive type theory of Coq Proof Assistant without adding any axiom to it and uses this framework to present a constructive proof of the Lovasz Replication Lemma, which is the central idea in the proof of Weak Perfect Graph Theorem.
On minimally circular-imperfect graphs
Chromatic number and subtrees of graphs
Let G and H be two graphs. We say that G induces H if G has an induced subgraph isomorphic to H: A. Gyárfás and D. Sumner, independently, conjectured that, for every tree T. there exists a function
A new decomposition theorem for Berge graphs
A hole in a graph is an induced cycle on at least four vertices. A graph is Berge if it has no odd hole and if its complement has no odd hole. In 2002, Chudnovsky, Robertson, Seymour and Thomas

Some properties of minimal imperfect graphs
Bull-free Berge graphs are perfect
TLDR
It is proved that bull-free Berge graphs are perfect; a part of the argument relies on a new property of minimal imperfect graphs.
About Skew Partitions in Minimal Imperfect Graphs
TLDR
This paper proves the conjecture that a minimal imperfect graph G cannot have a skew cutset S decomposable into disjoint sets A and B joined by all possible edges in the particular case where at least one of A andB is a stable set.
PERMANENTS, PFAFFIAN ORIENTATIONS, AND EVEN DIRECTED CIRCUITS
TLDR
A structural characterization of the feasible instances is proved, which implies a polynomial-time algorithm to solve all of the above problems.
Tutte's Edge-Colouring Conjecture
TLDR
It is shown that the conjecture that every 2-connected cubic graph not containing the Petersen graph as a minor is 3-edge-colourable is true, in general, provided it is true for two special kinds of cubic graphs that are almost planar.
