Hi python-list, hi Srinivas,
I managed to implement the mark&sweep approach for fast removal from
heaps. This way, I got three pleasant results:
1) a substantial speed up!
2) an improved testsuite
3) discovery and fixing of several bugs
@Srinivas I would be honored if you could have a look at the
implementation: https://github.com/srkunze/xheap . After all, it was
your idea. I only perform the sweeping step during pop and remove with
the condition of yours. :)
Using the original xheap benchmark
<http://srkunze.blogspot.de/2016/02/the-xheap-benchmark.html>, I could
see huge speedups: from 50x/25x down to 3x/2x compared to heapq. That's
a massive improvement. I will publish an update soon.
Best,
Sven
