This article aims to compose music melody suited for multiple users' feelings by employing parallel Distributed Interactive Genetic Algorithm (DIGA). In the DIGA, each user proceeds into a general Interactive Genetic Algorithm (IGA) process by evaluating solution candidates subjectively. In some...

An efficient estimator is constructed for the quadratic covariation or integrated covolatility matrix of a multivariate continuous martingale based on noisy and non-synchronous observations under high-frequency asymptotics. Our approach relies on an asymptotically equivalent continuous-time...
