Here you can show of your code, including embedded Jupyter Notebooks, GitHub gist or math:
$$ \gamma_{n} = \frac{ \left | \left (\mathbf x_{n} - \mathbf x_{n-1} \right )^T \left [\nabla F (\mathbf x_{n}) - \nabla F (\mathbf x_{n-1}) \right ] \right |}{\left \|\nabla F(\mathbf{x}_{n}) - \nabla F(\mathbf{x}_{n-1}) \right \|^2} $$Don’t forget to enable features you need in the config/_default/params.yaml (e.g. math support)
