What are the advantages and disadvantages of logic programming?

Logic programming has a number of advantages and disadvantages, and here are some of them:

Advantages:

• Logic programming can be used to express knowledge in a way that does not depend on the

implementation, making programs more flexible, compressed and understandable.

• It enables knowledge to be separated from use, ie the machine architecture can be changed

without changing programs or their underlying code.

• It can be altered and extended in natural ways to support special forms of knowledge, such

as meta-level or higher-order knowledge.

• It can be used in non-computational disciplines relying on reasoning and precise means of

expression.

Disadvantages:

• Initially, due to insufficient investment in complimentary technologies, users were poorly

served.

• In the beginning, poor facilities for supporting arithmetic, types, etc. had a discouraging

effect on the programming community.

• There is no adequate way of representing computational concepts found in built-in

mechanisms of state variables (as is usually found in conventional languages).

• Some programmers always have, and always will prefer the overtly operational nature of

machine operated programs, since they prefer the active control over the 'moving parts'.
