We introduce a general and in a certain sense time-optimal way of solving one problem after another, efficiently searching the space of programs that compute solution candidates, i...
In the present paper, the existence and multiplicity problems of extensions are addressed. The focus is on extension of the stable type. The main result of the paper is an elegant...
In many cases of disagreement it is impossible to demonstrate that either party is wrong. The role of argument in such cases is to persuade rather than refute. Following Perelman, ...
