## Formation and Dissolution Constraints for Exponential Family Random Graph Models

### Description

This page describes the network sample space constraints that are included with the `tergm` package. For more information, and instructions for using constraints, see `ergm-constraints` and `ergm`.

### Constraints implemented in the `tergm` package

`atleast(nw)`

  The Formation Constraint: Preserve all ties in network `nw`. Only dyads that are not ties in `nw` may be changed.

`atmost(nw)`

  The Dissolution Constraint: Prevent all nonties in network `nw`. Only dyads that have ties in `nw` may be changed.
