Can any help me remove the indentation of the text after defining an optimization equation using the optidef package?



The optimization problem is defined as
    % Optimization variable
    % Objective function
    {\frac{\left\lVert Z_{\text{FRAC}}(R,L_{\beta},\beta,\omega) - Z_{\text{FEA}}(\omega)\right\rVert^{2}}{\left\lVert Z_{\text{FRAC}}(R,L_{\beta},\beta,\omega) + Z_{\text{FEA}}(\omega)\right\rVert^{2}} \label{eq:objectiveFunction}}
    % Optimization problem label
    % Optimization results
    % Constraints
    \addConstraint{R}{> 0, \quad R &&\in \mathbb{R}}
    \addConstraint{L_{\beta}}{> 0, \quad L_{\beta} &&\in \mathbb{R}}
    \addConstraint{0 \leq \beta}{\leq 1, \quad \beta &&\in \mathbb{R} \label{eq:betaConstraint}}
where $Z_{\text{FRAC}}(R,L_{\beta},\beta,\omega)$ is the impedance calculated from the fractional model  and $Z_{\text{FEA}}(\omega)$ is the impedance determined by FEA.



  • Did you try adding \noindent?

  • @Bernard it does not help.

  • looks like a bug in the package. It's probably best to contact the package authors and ask them to take a look.

    @thymaro I've now opened an issue on their GitHub: github.com/jeslago/optidef/issues/29

The issue is fixed in the latest version of optidef on GitHub. Just download optidef.sty and add it to your working directory.
