Really nice article, @karjudev, but I noticed one small issue/error: The formula for the page rank z_i is malformed in that the sum-index is not under the sigma but right next to it instead.

Thank you for your appreciation! Actually the formula is well formed in LaTeX: z_i = \sum_{j \in \mathcal{I}_i} P_{ij} z_j. This could be a issue with KaTex on Dev.to that renders badly apexes and subscripts.
