George Polya
The undisputed father of mathematical problem solving is George Pólya (December 13, 1887 – September 7, 1985), one of the giants of classical analysis in the 20 century. He considered solving problems to be a practical art, one that can be taught and learned. His books on the subject How To Solve It (1945) and the two-volume set Mathematics and Plausible Reasoning (1954), and Mathematical Disco...
متن کاملBrain-specific polyA- transcripts are detected in polyA+ RNA: do complex polyA- brain RNAs really exist?
Transcripts encoded by 2 different rat genomic clones, rg13 and rg100, appear to be typical brain-specific polyA- RNAs, as defined by previous criteria (rare, polysomal, and postnatally expressed from single-copy genes). However, we have found by using a sensitive nuclease protection assay that low levels of these transcripts (10% and 3%, respectively) are detected in polyA+ RNA. To determine i...
متن کاملRubbery Polya Tree.
Polya trees (PT) are random probability measures which can assign probability 1 to the set of continuous distributions for certain specifications of the hyperparameters. This feature distinguishes the PT from the popular Dirichlet process (DP) model which assigns probability 1 to the set of discrete distributions. However, the PT is not nearly as widely used as the DP prior. Probably the main r...
متن کاملType Inference for PolyA
We present an automatic type inference algorithm for PolyA, a type system for Mobile Ambients presented in earlier work by us together with Torben Amtoft. We present not only a basic inference algorithm, but also several optimizations to it aimed at reducing the size of the inferred types. The final algorithm has been implemented and verified to work on small examples. We discuss some small pro...
متن کاملG . Polya , 1887 - 1985
Jakab was a lawyer in the Budapest office of the Assicurazioni Generali of Trieste, a large international insurance firm. Before joining the company he had had a private law practice. His real interests, however, lay in economics and statistics and he continued to study these on the side, in the hope of obtaining an academic position in economics, so that he could devote full time to research. ...
