Algorithms are a fundamental component of robotic systems. Robot
algorithms process inputs from sensors that provide noisy and
partial data, build geometric and physical models of the world,
plan high-and low-level actions at different time horizons, and
execute these actions on actuators with limited precision. The
design and analysis of robot algorithms raise a unique combination
of questions from many elds, including control theory,
computational geometry and topology, geometrical and physical
modeling, reasoning under uncertainty, probabilistic algorithms,
game theory, and theoretical computer science. The Workshop on
Algorithmic Foundations of Robotics (WAFR) is a single-track
meeting of leading researchers in the eld of robot algorithms.
Since its inception in 1994, WAFR has been held every other year,
and has provided one of the premiere venues for the publication of
some of the eld's most important and lasting contributions. This
books contains the proceedings of the tenth WAFR, held on June
13{15 2012 at the Massachusetts Institute of Technology. The 37
papers included in this book cover a broad range of topics, from
fundamental theoretical issues in robot motion planning, control,
and perception, to novel applications.

A Markov Decision Process (MDP) is a natural framework for
formulating sequential decision-making problems under uncertainty.
In recent years, researchers have greatly advanced algorithms for
learning and acting in MDPs. This book reviews such algorithms,
beginning with well-known dynamic programming methods for solving
MDPs such as policy iteration and value iteration, then describes
approximate dynamic programming methods such as trajectory based
value iteration, and finally moves to reinforcement learning
methods such as Q-Learning, SARSA, and least-squares policy
iteration. It describes algorithms in a unified framework, giving
pseudocode together with memory and iteration complexity analysis
for each. Empirical evaluations of these techniques, with four
representations across four domains, provide insight into how these
algorithms perform with various feature sets in terms of running
time and performance. This tutorial provides practical guidance for
researchers seeking to extend DP and RL techniques to larger
domains through linear value function approximation. The practical
algorithms and empirical successes outlined also form a guide for
practitioners trying to weigh computational costs, accuracy
requirements, and representational concerns. Decision making in
large domains will always be challenging, but with the tools
presented here this challenge is not insurmountable.
