As for toric Fano manifolds, Galkin, Golyshev and Iritani([8]) proved Gamma con- jectures I, II modulo Conjecture O, and then Galkin ([6]) has made some progress on Conjecture O

While we have provided some theoretical arguments (asymptotic expansion in the finite-dimensional case, convergence to optimal predictions in the infinite- dimensional case), a

It combines indica- tor-based selection based on the contributing hypervolume with the efficient strategy parameter adaptation of the elitist covariance matrix adaptation

In this contribution we use methods of optimal control theory to compute the optimal step length of the Newton method on the class of self-concordant functions, as a function of

In particular, several adaptive algorithms have been pro- posed for the optimization of the Constant Modulus cost func- tion including the adaptive Analytical CMA (ACMA) in
