16-899C ACRL Tetris Reinforcement Learner

Our approach to this problem was to use reinforcement learning with a function approximator to approximate the state value function [RSS98]. In our case, a +1 reward was given for every completed line, so that the value function would encode the long-term number of lines that is going to be completed by the algorithm. In order to achieve this, we extract features from the game state, and use gr...

June 1984 LIDS - P - 1387 DISCRETE - TIME PRIORITY QUEUES WITH PARTIAL INTERFERENCE

A class of discrete time priority queueing systems with partial interference is considered. Packet-radio communication networks that use a certain mode of operation fall into this class. In these systems N nodes share a common channel to transmit their packets. One node uses random access scheme while the other nodes use the channel according to prescribed priorities. Packet arrivals are modele...
