 ## Controlling the Kuramoto Sivashinsky Equation
 
-Our work aims to minimize the dissipation and power consumption of a system whose dynamics are governed by the Kuramoto-Sivashinsky equation.
+Our work aims to minimize the dissipation and power consumption of a system whose dynamics are governed by the Kuramoto-Sivashinsky equation. An example of the system and its rewards where a controller applies random actions to it is illustrated below.
