C++ k shortest paths algorithm

Does someone know if there is any production-ready K-shortest-paths algorithm for C++?

The only available implementation (k-shortest-paths), unfortunat开发者_JAVA百科ely, leaks memory, has counter-intuitive interfaces and another "reinvented wheel" - the Graph class.

I'm looking for something better, probably, boost::graph-based.

There are two possible algorithms available - simple Yen's algorithm and optimized Yen's algorithm, both would suit me.

Thanks in advance.

There is another one, but you'll have to check if this also leaks memory.
