Notes 6.4.2 Control Knowledge

An algorithm comprises: logic component, that mentions the knowledge to be utilized in solving
problems, and manage component, that identifies the problem-solving approaches by means of
which that knowledge is utilized.
Therefore, Algorithm = Logic + Control. The logic component identifies the meaning of the
algorithm while the control component only affects its competence. An algorithm may be
formulated in dissimilar manners, generating similar behavior. One formulation, may have a
apparent statement in logic component but utilize a complicated problem solving strategy in
the control component. The other formulation may have a complex logic component but utilize
a simple problem-solving approach. The competence of an algorithm can frequently be improved
by enhancing the control component without altering the logic of the algorithm and thus without
altering the meaning of the algorithm.

The approach in databases is towards the division of logic and control. The programming
languages these days do not differentiate between them.
Computer programs will be more frequently accurate, more simply enhanced, and more readily
adapted to new troubles when programming languages divide logic and control, and when
execution mechanisms offer more powerful problem-solving amenities of the type given by
intelligent theorem-proving systems.

Did u know? The programmer mentions both logic and control in a single language.

!

Caution The execution mechanism utilizes only the most rudimentary problem-solving
capabilities.

6.5 Summary

 In Declarative knowledge representation, knowledge is signified as static collection of
details which are influenced by common procedures.
