What is mixed strategy in Game Theory?

Updated May 16, 2026

Short answer

A mixed strategy assigns probabilities to different actions instead of choosing one deterministic action.

Deep explanation

Mixed strategies allow players to randomize actions to avoid predictability. This is essential in games where no pure strategy Nash equilibrium exists.

Real-world example

Used in cybersecurity to randomize defense strategies.

Common mistakes

  • Thinking randomness means irrational behavior.

Follow-up questions
