# gf_lpa

Label propagation algorithm (LPA)

## Description

Run static Label Propagation for detecting communities in networks. Each node in the network is initially assigned to its own community. At every iteration, nodes send their community affiliation to all neighbors and update their state to the mode community affiliation of incoming messages. LPA is a standard community detection algorithm for graphs. It is very inexpensive computationally, although (1) convergence is not guaranteed and (2) one can end up with trivial solutions (all nodes are identified into a single community).

## Usage

`gf_lpa(x, max_iter, ...)`

## Arguments

Argument | Description |
---|---|

x | An object coercable to a GraphFrame (typically, a `gf_graphframe` ). |

max_iter | Maximum number of iterations. |

… | Optional arguments, currently not used. |

## Examples

```
<- gf_friends(sc)
g gf_lpa(g, max_iter = 5)
```
