The present paper does not claim to be a description of the TGTSystem, since it was already presented by Professor Friedman herself at the International Conference on Computational Linguistics in Stockholm in 1969. In addition the system has been described also in the book Jo'i'cE FRIEDMAN, A Computational Model of Transformational Grammar, Elsevier, 1971. Our intention is to present the new in...

easyJet, one of Europe’s most successful low-cost short-haul airlines, has a simple pricing structure. For a given flight, all prices are quoted one-way, a single price prevails at any point, and, in general, prices are low early on and increase as the departure date approaches.

In this paper, we generalize the Ski-Rental Problem to the Bahncard Problem which is an online problem of practical relevance for all travelers. The Bahncard is a railway pass of the Deutsche Bundes-bahn (the German railway company) which entitles its holder to a 50% price reduction on nearly all train tickets. It costs 240 DM, and it is valid for 12 months. For the common traveler, the decisio...

This paper considers an optimal control perspective on dynamic power price problem where the load on the power-grid is controlled via price. The optimal regulatory price is characterized by inverse variational inequality in which the function value and the control variable are in the opposite positions of the classical variational inequality. Discrete and continuum models with load constraints ...
