Roberto Cereceda
Roberto Andrés Cereceda Guajardo (born 10 October 1984) is a Chilean footballer, who currently plays for Chilean club Audax Italiano. Club career Audax Italiano Cereceda started in the youth ranks of Colo-Colo before moving to another Santiago club, Audax Italiano. In 2002, Cereceda made his professional debut with Chilean club Audax Italiano. Cereceda made 93 caps with Audax and scored six goals in the five years he played with the first team. Audax made their first appearance in international competition in 2007, in which Cereceda participated. In the third group match against Alianza Lima of Peru, Cereceda scored his first goal in international competition in the 3-1 victory. The team along with Cereceda tied with São Paulo of Brazil with 11 points in group play but failed to make the second round due to goal differential. His play in the tournament and in the national tournament led him to return to his former club Colo-Colo. Colo-Colo Prior to the 2007 Torneo Clausura ...

Cereceda's Conjecture
In the mathematics of graph coloring, Cereceda’s conjecture is an unsolved problem on the distance between pairs of colorings of sparse graphs. It states that, for two different colorings of a graph of degeneracy , both using at most colors, it should be possible to reconfigure one coloring into the other by changing the color of one vertex at a time, using a number of steps that is quadratic in the size of the graph. The conjecture is named after Luis Cereceda, who formulated it in his 2007 doctoral dissertation. Background The degeneracy of an undirected graph is the smallest number such that every non-empty subgraph of has at least one vertex of degree at most . If one repeatedly removes a minimum-degree vertex from until no vertices are left, then the largest of the degrees of the vertices at the time of their removal will be exactly , and this method of repeated removal can be used to compute the degeneracy of any graph in linear time. Greedy coloring the vertices in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
