 ## Features
 - Models solar cells as unbiased pn diodes under illumination using SDE and DDE.
 - Incorporates effects of parasitic resistances: **Series Resistance (Rs)** and **Shunt Resistance (Rsh)**.

 ### Fitness Function
 The GA minimizes the error between measured and calculated current values:
 
-\[
-f = \sqrt{\frac{1}{n} \sum_{j=0}^{n} \left(\frac{I_{j, \text{measured}} - I(V_j)}{I_{j, \text{measured}}}\right)^2}
