Motsamai Molefe,Nolubabalo Lulu MagamOne of the aims of the section is to set up a framework that would allow one to analyze behavior of algorithms at large, to study expected or average properties of algorithms, or its behavior on “most” inputs. The key point here is to equip algorithmic problems with probability distributions on their sets of instances.

: Initiating Children in Language and WorldIn this chapter, following [48], we show that the .-complete problems Subset Sum and 3-Sat have low generic complexity. As it is well known that these problems are easy most of the time, these results confirm our expectations. The difficult instances are rare: we discuss them, too.

Background on Computational ComplexityIn all instances, if not said otherwise, we use Turing machines as our principal model of computation. In this section we briefly recall some basic definitions and notation concerning Turing machines that are used throughout this chapter.

Generic Complexity of NP-complete ProblemsIn this chapter, following [48], we show that the .-complete problems Subset Sum and 3-Sat have low generic complexity. As it is well known that these problems are easy most of the time, these results confirm our expectations. The difficult instances are rare: we discuss them, too.
