Wow! The last version of the Boost C++ libraries contains Boost.Heap a new library that implements several type of the priority_queue ADT: binomial heap, d-ary heap, Fibonacci heap, skew heap, and pairing heap.

I think this library fill a big gap in the STL C++ library. Now, to implement an fairly efficient version of Dijkstra's algorithm should be much easier...

I like this kind of schools:

"The school will also feature a substantial amount of *hands-on sessions*, organized by Laurent Perron, using the "Google or-tools" system (participants should bring their laptops)."
The 9th edition of the ACP Summer School will be held in Bologna, from June 16 to June 20. This year topic is "Practical Constraint Programming" and the school is meant for CP researchers and practitioners with an academic or industrial background, interested in using Constraint Programming and ...

Google Scholar Alert

If you don't use it already, I recommend you this service. You get email notifications about papers that match the query that you have specified when you have created the alert. I have just added my fifth alert with keywords "resource constrained" "shortest path"... already at the creation of the alert, I have found two interesting papers!

Gurobi 5.0 is coming

My favorite two new features in the list:
- new interface to R. After Python, also R is more popular than ever in the OR community
- Support for Lazy Constraints (they can be useful for solving old-fashioned academic combinatorial problems via LP, e.g., max stable set)
