August 3, 2015: I am on vacation... from academic bureaucracy! I am reading "Évariste", a historical novel based on the life of Évariste Galois (par FrançoisHenri Désérable, chez Gallimard, 2015). 
July 26, 2015:
In the seventies/eighties, papers on algorithms for
nonlinear optimization would start by "local convergence",
and in the eighties/nineties by "global convergence".
At that time, there was a huge excitement about polynomial
complexity of interiorpoint methods. I still remember well
Professor Richard Tapia saying once in class that such a polynomial
complexity was a qualified form of global convergence
(indeed the starting point was arbitrary).

March 19, 2015: In the paper Direct search based on probabilistic descent (see papers), there is a new proof technique for establishing global rates and worst case complexity bounds for randomized algorithms for which the new iterate depends on some object (directions, models) and the quality of the object is favorable with a certain probability. The technique is based on counting the number of iterations for which the quality is favorable and examining the probabilistic behavior of this number. 
March 19, 2015: I'm starting a miniature blog here... I hope I'll have something interesting to say once in a while...
