Final Review

Front

In an influence diagram, decision nodes are represented by?

Back

Squares or rectangles.

Front

What is a nonlinear function?

Back

A function that contains terms with variables raised to powers other than 1, including constants multiplied by products of variables.

Front

True or False: The multistart feature in Solver can be used for nonlinear programming problems to systematically try a number of different starting points.

Back

True.

Front

What is the most appropriate accuracy measure for comparing forecasting methods for different time periods?

Back

MAPE (Mean Absolute Percentage Error).

Front

True or False: Evolutionary Solver uses an algorithm based on genetics, evolution, and survival of the fittest.

Back

True.

Front

What are decision nodes in influence diagrams?

Back

They represent choices or decisions that need to be made.

Front

What does MAPE stand for?

Back

Mean Absolute Percentage Error.

Front

What is the significance of nonlinear functions in mathematics?

Back

They model relationships that are not proportional, allowing for more complex behaviors.

Front

What is the role of the multistart feature in optimization problems?

Back

It helps find better solutions by exploring multiple starting points.

Front

What is the difference between MSE and MAPE?

Back

MSE (Mean Squared Error) measures average squared differences, while MAPE measures accuracy as a percentage.
