The QField serves to recreate the process of reinforcement learning with a piece of paper and a pen. This is about learning a way by using the unplugged algorithm. Unlike other algorithms that aim for optimal solutions, this approach focuses on learning through trial and feedback.<\/p>\n\n\n\n\n\n\n\n

Preparation<\/h3>\n\n\n\n

Print out the picture or draw it (instead of Scratch you can also write 'Start' in the first field and instead of the pie 'Goal'). You also need a piece of play (as with humans, don't get angry).<\/p>\n\n\n\n

Scratch first moves randomly across the field.<\/p>\n\n\n\n

The small scratch program shows you the direction in which you drag your figure (if possible), click on the green flag or directly on the arrow.<\/p>\n<\/div>\n\n\n\n
