Blog on the move

This blog is now merged with my primary blog "The Perspective Dimension" due to operational ease. Here is the link to the new blog: http://paradoxsolutions.blogspot.com/

Henceforth no new posts will appear in this blog. Thank you, if you have been following the posts. Hope to see your continued interest at the new address!

Visual Search Problem

Visual perception accomplished in our brains is a fascinating process. There are many interesting features that one comes across. One of them is the visual search problem - the objective is to identify an odd image amidst a group of distractor images in the shortest time. Put differently, certain kind of symbols are more easily recognizable when placed amidst a group of similar looking symbols whilst others are not. For instance - symbol 'V' amidst symbol '^'s (inverted V) are very easy to spot. On the other hand, symbol 'S's are much more difficult to spot amidst symbol '2' (mirrored S).

I could personally relate to this phenomenon while solving a 3x3 Sudoku
