This paper shows the advantages of amalgamating functional and logic
programming languages. In comparison with pure functional languages,
an amalgamated functional logic language has more expressive power.
In comparison with pure logic languages, functional logic languages
have a better control behaviour. The latter will be shown by presenting
methods to translate logic programs into a functional logic
language with a narrowing/rewriting semantics. The translated programs
produce the same set of answers and have at least the same efficiency
as the original programs. But in many cases the control behaviour
of the translated programs is improved.
This requires the addition of further knowledge to the programs.
We discuss methods for this and show the gain in efficiency
by means of several examples.
