The two-armed bandit problem is a simplified version of a fundamental challenge faced by any controller of a non-deterministic system without comprehensive knowledge about the system.

This problem revolves around maximizing expected revenue from tossing two coins, labeled A and B, while simultaneously learning about each coin's bias.

Understanding the intricacies of this problem provides insight into managing conflicting objectives in decision-making.

Element 1: The Fundamental Conflict:

• The two-armed bandit problem boils down to a basic conflict in decision-making, which every controller of a non-deterministic system encounters.

• The challenge lies in balancing two distinct objectives: maximizing immediate gains and improving future decision-making by increasing knowledge of the system.

Element 2: The Dual Objectives:

• The experimenter in the two-armed bandit problem has to tackle two aims with each toss of the coins.

• The first is to maximize the expected revenue by choosing the coin believed to be biased towards the favorable outcome.

• The second is to learn more about the biases of each coin, ideally by selecting the coin about which he knows the least.

Element 3: The Inherent Conflict:

• The conflict arises because the objectives of maximizing immediate gains and increasing knowledge about the system are fundamentally at odds.

• The coin that the experimenter knows the least about may not be the one that maximizes immediate revenue, thereby creating a tug-of-war between short-term profit and long-term understanding.
