PR(A) | = 0.15 + 0.85 * 1 = 1 |

### How do you implement PageRank?

chonyy/PageRank-HITS-SimRank

- Initialize the PageRank of every node with a value of 1.
- For each iteration, update the PageRank of every node in the graph.
- The new PageRank is the sum of the proportional rank of all of its parents.
- Apply random walk to the new PageRank.
- PageRank value will converge after enough iterations.

## How can we assign a PageRank score to each node of the graph?

graph with two directed edges for each undirected edge. Damping parameter for PageRank, default=0.85. key for every graph node and nonzero personalization value for each node. By default, a uniform distribution is used.

## What is valuable in increasing a PageRank?
