On the Behavior of the Gradient Norm in the Steepest Descent Method (ResearchIndex)

"It is well known that the norm of the gradient may be unreliable as a stopping test in unconstrained optimization, and that it often exhibits oscillations in the course of the optimization."

Adjacency matrix - Wikipedia

If A is the adjacency matrix of the directed or undirected graph G, then the matrix An (i.e. the matrix product of n copies of A) has an interesting interpretation: the entry in row i and column j gives the number of (directed or undirected) paths of length n from vertex i to vertex j.

Critical Section - The Emperor's New Code: "It was interesting that in Don Box' introduction to Indigo at the PDC, he asked the roomful of developers 'how many people have successfully deployed DCOM?' Nobody raised their hands. 'How many people have successfully deployed .NET remoting?' Nobody raised their hands. 'How many people have successfully deployed CORBA?' Only a few hands. Out of 3,000 developers essentially none had successfully deployed an object-oriented remote communication method. It is good that Microsoft has abandoned OO and embraced SOA."
