I’ve added a few shots from a recent trip to the west coast of Canada and the U.S. — Vancouver, Victoria, Seattle and San Francisco. Enjoy!

Version 1.2.0 of the dysii Dynamic Systems Library is now available. The new release adds the Auxiliary Particle Filter, a generalised framework for particle filter resampling strategies, and makes a number of optimisations and bug fixes.

Specific changes include:

• Added auxiliary particle filter.
• Added generalised resampling strategy framework.
• Fixed diagonal covariance detection for optimised Gaussian density calculations.
• Fixed several serialization bugs.
• Fixed Wiener process variance bug.

See the updated documentation and VERSION.txt file in the new distribution for more information.
