# AICN

The `AICN` solver implements a damped Newton method.

[arXiv:2211.00140](https://arxiv.org/abs/2211.00140)

## Syntax

```
solver AICN (1) [2]
# (1) int, unique solver tag
# [2] double, approx. length, default: 1.0
```

## Remarks

1. `AICN` is an alternative to the [`Newton`](newton) solver.

For example usage, see [this](https://github.com/TLCFEM/suanPan-manual/blob/dev/docs/Example/Miscellaneous/advanced-solver.md) example.
