Just 2 days left: Genetic Programming and Evolvable Machines anniversary issue available for free!

The Springer journal Genetic Programming and Evolvable Machines is celebrating its first 10 years with a special anniversary issue of articles reviewing the state of the field and considering some of its possible futures. For the month of July the entire issue is available for free!

Cover of the journal of Genetic Programming and Evolvable Machines

A momentary interruption in the (slow) posting on the road trip (which has been done for nearly two weeks now!) to provide a time sensitive plug for those of you interested in genetic programming, evolutionary computation, and the like.

The Springer journal Genetic Programming and Evolvable Machines is celebrating its first 10 years with a special anniversary issue of articles reviewing the state of the field and considering some of its possible futures. For the month of July (which ends in two days!) the entire issue is available for free download.

Included in the issue are:

  • Human-competitive results produced by genetic programming
  • Theoretical results in genetic programming: the next ten years?
  • Genetic Programming and Evolvable Machines: ten years of reviews
  • Open issues in genetic programming
  • Grammar-based genetic programming: a survey
  • Developments in Cartesian Genetic Programming: self-modifying CGP
  • Bio-inspired artificial intelligence: theory, methods, and technologies

Once the month ends these will all start costing money again with two exceptions: the article on human-competitive results and the survey of 10 years of reviews will remain free in perpetuity.

In the spirit of full disclosure, I’m on the editorial board of the journal and contributed to one of the articles. Still, it’s a cool resource marking an interesting time in the development of the field, so take advantage of it while you can!

One of the best walking robot demos I’ve ever seen

Wow – this is quite amazing. About mid-way through Big Dog (a defense project from Boston Dynamics) slips on some glaze ice and recovers without actually falling down, which involves some super cool real-time responses. The video is long-ish, but definitely worth the investment.

I’d love to know what the burn out rate for the joints and motors are. One of the amazing things about biological organisms is that we can balance muscles against each other to hold a position without wearing ourselves out. Many walking robots, on the other hand, end up exerting so much force in simply maintaining their position that they tend to burn out key components really quickly. Given the responses and forces involved in Big Dog’s movement and balance, you’d think they’d have this problem in spades. If these trials go on for any length of time, however, they presumably managed to handle this to some degree. Their web site says “BigDog’s legs are articulated like an animal’s, and have compliant elements that absorb shock and recycle energy from one step to the next.”; the idea of recycling energy back into the motion (use it instead of fight it) certainly looks promising.

The research is being funded by DoD money, with the hope that robots like this could help carry material in the field. I could imagine nice civilian applications, however. An infirm person in Morris, for example, might be capable of walking to the grocery store, but not capable of carrying a shopping load home. A smaller, electric version of this could be a nice alternative to cars in that situation.

Thanks to Sub-Evil for the pointer!
