Scientists have developed an exact approach to a key quantum error correction problem once believed to be unsolvable, and have shown that what appeared to be hardware-related errors may in fact be due ...

So, Gaucher and researcher coordinator Randall pitted the contemporary model-based, or "maximum likelihood," algorithms in a race against the generic, or "parsimony," algorithm.

In this paper, we propose smoothing algorithms for rating-level PD and rating migration probability. The smoothed estimates obtained by these approaches are optimal in the sense of constrained maximum ...

Recent phylogenetic analyses have turned away from maximum parsimony towards the probabilistic techniques of maximum likelihood and bayesian Markov chain Monte Carlo (BMCMC).

A team of researchers led by Rasmus Kinn of the Swiss Federal Institute of Technology in Zurich has created a near-perfect algorithm to calculate the maximum transport flows at the lowest cost in ...
