# Search problem

The problem of determining whether a given value occurs in a given list

## Description

The search problem is an algorithmic problem as follows:

• Input:
• A list l of values
• A value v
• Output:
• True: v occurs in l.
• False: otherwise.
This is an algorithmic problem because one can obviously define an algorithm to iterate over the elements of l and to check for an occurrence of v along the way. This simple idea is the foundation for linear search. When additional constraints are imposed on the input, then search may also be more efficient; see binary search for example.
