I would like to store and later read an unordered_map in a memory-mapped file using C++ on Solaris (compiler g++ 4.9.2). I have quite a large data that needs to be stored as a key-value pair. But, maintaining an unordered_map in memory takes up lot of me
If you need to iterate through the keys of a dictionary in sorted order, then you can pass your dictionary as an argument to sorted(). You’ll get a list containing the keys in sorted order. This list will allow you to traverse your dictionary sorted by keys:...

While some of these results might be better than the original random sorting, they aren't what I would expect to be a useful colormap for plotting anything. There isn't a way to traverse the set of points without one or more aspect of the color progression becoming cyclic. I picked the...
Schematic outline of typical processing and analysis steps for 3D plant phenotyping. Through an active (1.a) or passive (1.b) 3D acquisition method, either a depth map (2.a), a point cloud (2.b) or a voxel grid (2.c) is obtained. After a number of preprocessing steps consisting of...
