[Blog Post] Spatial Spread And Conditional Character Entropy Reduction

[MichelleL11]

For Anton or anyone else interested in the possible integration of these ideas with the Polybius cipher:

Here is a recent article, You are not allowed to view links. Register or Login to view., Arroyo et al. (2020) that includes a lot of interesting adaptions of the Polybius square.  The literature review starts in 1996, so it's all recent stuff -- but some of it is relatively straightforward and definitely could have been done without computers if the idea of the Polybius Square was known.

I had hoped there would be some discussion of the history but, alas, no -- but wanted to provide this reference and all the citations in it as possible inspirations for possible adaptions.
