due to successes of fingerprinting method in producing rapid and low-cost information of sediment sources, in this research this method was used in three sub-cathments of chasht-khoran basin in semnan province: amrovan, atari and ali-abad. samples below 63 μm were separated and 15 fingerprinting propertis was measured. in the first stage comparison of means and differentiation analysis were use...

Some of the cultural and technical forces that influenced the creation of the “man” (the player-controlled element) in two early home video games, Pitfall! and Yars’ Revenge, are discussed. We find that the specific nature of the Atari Video Computer System (also known as the Atari VCS and Atari 2600) as a computing platform enables and constrains what can be done on the system, and that it als...

The asynchronous nature of the state-of-the-art reinforcement learning algorithms such as the Asynchronous Advantage ActorCritic algorithm, makes them exceptionally suitable for CPU computations. However, given the fact that deep reinforcement learning often deals with interpreting visual information, a large part of the train and inference time is spent performing convolutions. In this work we...

We experimented a simple yet powerful optimization for Monte-Carlo Go tree search. It consists in dealing appropriately with strings that have two liberties. The heuristic is contained in one page of code and the Go program that uses it improves from 50 % of won games against Gnugo 3.6 to 76 % of won games.
