[mkgmap-dev] splitter: No solution found

From GerdP gpetermann_muenchen at hotmail.com on Sun Jul 27 06:39:37 BST 2014

Hi Andrzej,

I can't reproduce the problem on my machine because I only have 8GB
mem and the grid for south-america with resolution=16 requires more,
so debugging is a pain as the machine is constantly swapping.

I tried todays south-america-latest.osm.pbf with resolution=15 and r412
finds a 
rather good solution with 104 tiles. 

Do you have a good reason to use resolution=16 ?
I think this value is useful for small input files, but I see no 
need to use it with such a large one. It just seems to blow up
the amount of data.

I have an idea how to improve the algo if 
the "No solution found for partition..." message
is written. I'll try to produce my own case with a smaller sample set
to reproduce the problem.

Gerd
