Course content

This subject will from autumn 2007 be replaced by INF2220

Basic data structures such as stacks, trees, graphs, hash tables and
priority queues, together with algorithms for traversing and
manipulating these structures. Different implementations are covered,
with emphasis being put on efficiency, program structure and abstract
data types. Different sorting algorithms will be examined. Important
elements in the course include recursive programming as well as
evaluation and description of program efficiency.

Learning outcome

Learn to solve practical and complex problems where the choice of data structures and appropriate algorithms is essential to implement effective programs with acceptable time and space requirements. Students shall also be able to decide if a given problem can be given an efficient implementation at all.
