Towards in-place geometric algorithms and data structures
For many geometric problems, there are efficient algorithms that use surprisingly very little extra space other than the given array holding the input. For many geometric query pr...

Geometrical interpretation and improvements of the Blahut-Arimoto's algorithm
The paper first recalls the Blahut Arimoto algorithm for computing the capacity of arbitrary discrete memoryless channels, as an example of an iterative algorithm working with pro...
