you're trying to use reinforcement learning to build a path planning system for an indoor autonomous robot. You want it to enter a specific room the end-user specifies, so you define a reward function to give a huge positive reward when it enters that room. After training, you notice some strange behaviour what do you notice?

• nothing, everything works as intended.
• the robot avoids the room
• once the robot enters the room, it never leaves.
• once it gets to the room, the robot enters and exits the room endlessly

which of the following is false about reinforcement learning?

• find a model which yields the greatest average expected reward
• reinforcement learning is a award based learning
• reinforcement learning is a type of supervised learning
• reinforcement learning is an online learning
