This week, at the Institute for Electrical and Electronics Engineersinternational Conference on Robotics and Automation, a group of MIT researchers were nominated for two best-paper awards for a new algorithm that can significantly reduce robot teamsplanning time.
The plan the algorithm produces may not be perfectly efficient, but in many cases, the savings in planning time will more than offset the added execution time.

Its speech compression algorithms are more complex and powerfulthan those used for the decade-old HD Voice system,
The codec also includes other algorithms developed to compress music. The separate algorithms are vital
because speech and music are compressed in different ways. Voice compression typically relies on algorithms called code-excited linear prediction (CELP),
which is built on the physics underlying the human vocal system. CELP can reduce the data rate of voice signals by about a factor of 10. hat coding did a good job on speech

The music part is the latest low-latency version of the AAC algorithm, developed for real-time streamed communications.
