The use of simulation models is desirable because they can usually be solved in one pass without incurring the time and cost of iterations. State true or false.

LCS stands for

• Learning classes system
• Learning classifier systems
• Learned class system
• None

An advantage of simulation is that it allows model builders to solve problems with minimal interaction with users or managers. State true or false.

Time compression in a simulation allows managers to test certain strategies with less risk. State true or false.

Simulation solutions cannot easily be transferred from one problem domain to another. State true or false.

Determining the duration of the simulation occurs before the model is validated and tested. State true or false.

Discrete events and agent-based models are usually used for middle or low levels of abstraction. State true or false.

In steady-state plant control design, the time-independent simulation would be appropriate. State true or false.

The simulation does not usually allow decision makers to see how a solution to a complex problem evolves over (compressed) time, nor can decision makers interact with the simulation. State true or false.

Visual interactive simulation (VIS) is a simulation method that lets decision-makers see what the model is doing and how it interacts with the decisions made, as they are made. State true or false.

Visual interactive modeling (VIM) systems, especially those developed for the military and the video-game industry, have "thinking" characters who can behave with a relatively high level of intelligence in their interactions with users. State true or false.

Blind search is different from optimization because

• It cannot result in optimal solutions whereas optimization methods do.
• It represents a guided approach whereas optimization follows an unguided approach.
• It usually does not conclude in one step like some optimization methods.
• It is usually a more efficient problem solving approach than optimization.

In modeling, an optimal solution is understood to be

• A solution that can only be determined by an exhaustive enumeration and testing of alternatives.
• A solution found in the least possible time and using the least possible computing resources
• A solution that is the best based on criteria defined in the design phase
• A solution that requires an algorithm for determination.

When is a complete enumeration of solutions used? 

• When a solution that is "good enough" is fine and good heuristics are available

What is not true about Heuristics ?

• Heuristics are used when the modeler requires a guided approach to problem solving.
