# What is the maximin criterion?

## What is the maximin criterion?

The Maximin criterion is a pessimistic approach. It suggests that the decision maker examines only the minimum payoffs of alternatives and chooses the alternative whose outcome is the least bad.

## What is maximin criterion example?

Maximin Criterion Except instead of taking the largest number under each action, you take the smallest payoff under each action (smallest number in each column). You then take the best (largest of these). The smallest payoff if you buy 20, 40, 60, and 80 bicycles are \$50, -330, -650, and -970 respectively.

Who formulated maximin criterion?

The game of Wald’s maximin model is also a 2-person zero-sum game, but the players choose sequentially. With the establishment of modern decision theory in the 1950s, the model became a key ingredient in the formulation of non-probabilistic decision-making models in the face of severe uncertainty.

How do you get a maximin strategy?

Maximin Strategy = A strategy that maximizes the minimum payoff for one player. The maximin, or safety first, strategy can be found by identifying the worst possible outcome for each strategy. Then, choose the strategy where the lowest payoff is the highest.

### What is the meaning of maximin?

: the maximum of a set of minima especially : the largest of a set of minimum possible gains each of which occurs in the least advantageous outcome of a strategy followed by a participant in a situation governed by game theory — compare minimax.

### What are the different criterions used for decision under uncertainty explain?

Maximizing the maximum possible payoff- the maximum criterion(optimistic). Maximizing the minimum possible payoff- the maximum criterion(pessimistic). Minimizing the maximum possible regret to the decision maker- The minimax criterion(regret).

What is Hurwicz criterion?

The Hurwicz criterion is arguably one of the most widely used rules in decision-making under uncertainty. It allows the decision maker to simultaneously take into account the best and the worst possible outcomes, by articulating a “coefficient of optimism” that determines the emphasis on the best end.

What is regret criterion?

By Robert J. Graham. The mini-max regret criterion in managerial economics bases business decisions on the maximum regret associated with each action. Regret measures the difference between each action’s payoff for a given state of nature and the best possible payoff for that state of nature.

#### Is Nash Equilibrium the best outcome?

Unlike dominant strategy, the Nash equilibrium doesn’t always lead to the most optimal outcome, it just means that an individual chooses the best strategy based on the information they have.

#### How many stages are there in decision-making?

7 decision-making process steps. Though there are many slight variations of the decision-making framework floating around on the Internet, in business textbooks, and in leadership presentations, professionals most commonly use these seven steps.

What is the Maximax criterion in decision theory?

maximax criterion. In decision theory, the optimistic (aggressive) decision making rule under conditions of uncertainty. It states that the decision maker should select the course of action whose best (maximum) gain is better than the best gain of all other courses of action possible in given circumstances. Click to read more on it.

Which is the working method of the decision criterion?

Since this decision criterion locates the alternative strategy that has the least possible loss, it is also known as a pessimistic decision criterion. The working method is: (i) Determine the lowest outcome for each alternative.

## What is the maximax strategy in game theory?

A maximax strategy is a strategy in game theory where a player, facing uncertainty, makes a decision that yields the ‘best of the best’ outcome. All decisions will have costs and benefits, and a maximax strategy is one that seeks out where the greatest benefit can be found.

## What is the maximin rule for making decisions?

Maximin. The maximin rule involves selecting the alternative that maximises the minimum pay-off achievable. The investor would look at the worst possible outcome at each supply level, then selects the highest one of these. The decision maker therefore chooses the outcome which is guaranteed to minimise his losses.
