What does "Minimize algebraic loop occurrences" actually do?

I have been warned of an algebraic loop in a Simulink model. One of the suggested actions is:

"This algebraic loop may be resolved when the subsystem option 'Minimize algebraic loop occurrences' is selected on some or all of the atomic and enabled subsystems in this algebraic loop."

The help page for 'Minimize algebraic loop occurrences' (https://uk.mathworks.com/help/simulink/gui/minimize-algebraic-loop-occurrences.html) doesn't really explain what Simulink is doing when the box is ticked.

Can someone explain?

Hi Miles,

This parameter directs Simulink to try to eliminate the algebraic loop that contains an atomic subsystem, when it simulates the model. You can read more about this in the following link that also shows different examples.
