This paper discusses the CARA programming environment for robot manipulators. The environment is realized as the integration of a full-edged logic system with a real-time robotic machine. While the development of a general robot programming environment is an elusive goal, exible development and in-cremental reenement are made possible by the open nature of the CARA environment.

We present two efficient network propagation algorithms that operate on a binary tree, i.e., a sparse-edged substitute of an entire similarity network. TreeProp-N is based on passing increments between nodes while TreeProp-E employs propagation to the edges of the tree. Both algorithms improve protein classification efficiency.
