Alfred Kempe published a false "proof" of the four colour theorem in 1879 which stood until Heawood showed the mistake 11 years later. The 'proof' is however still the basis for the computer aided proof discovered 100 years later.

It will take place from June 3 to 9, 2018 in Arco, Province of Trento, Italy. It will be the 20th edition of this conference held in Italy--the first one in 1981, the second in 1982, and every two years ever since--with the participation of many experts in finite geometries and their applications from all over the world. The main themes of the conference will be Finite Geometries, Incidence Structures, Combinatorial Designs and Graph Theory. Arc

International Symposium on Combinatorial Optimization Marrakesh, Morocco, April 11-13 2018 HOME COMMITTEES DATES INVITED SPEAKERS VENUE ACCOMODATIONS REGISTRATION SCHOOL SUBMISSION ISCO (International Symposium on Combinatorial Optimization) is a biennial symposium with its first issue held in Hammamet, Tunisia in March 2010, its second one in Athens, Greece in April 2012, its third one in Lisbon, Portugal in March 2014, and its fourth one in Vietri, Italy in May 2016. The symposium aims to bring together researchers from all the communities related to combinatorial optimization, including algorithms and complexity, mathematical programming and operations research. It is intended to be a forum for presenting original research in these areas and especially in their intersections. Quality papers on all aspects of combinatorial optimization, from mathematical foundations and theory of algorithms to computational studies and practical
