Using a fixed point relation based on the logarithmic derivative of the k-th order of an algebraic polynomial and the definition of the k-th root of a disk, a family of interval methods for the simultaneous inclusion of complex zeros in circular complex arithmetic was established by Petković...

Intractable maximum likelihood problems can sometimes be finessed with a Monte Carlo implementation of the EM algorithm. However, there appears to be little theory governing when Monte Carlo EM (M C E M) sequences converge. Consequently, in some applications, convergence is assumed rather than...
