This is the most valued option by BOOLE-DEUSTO users. It is possible that the user does not want to see the BOOLE solution, but she prefers to input her solution and BOOLE will tell her whether it is correct or not. In this case, the reader has to load the V-K and then activate the option Learning Mode. Once this is done, it is necessary to draw the circles with mouse clicks: with the left button the cells are selected and with the right button the circle is created. Once this is done, when you activate Evaluate Solution, BOOLE will indicate us if the solution presented is correct or not.
