Course Motivation
Need to run computer programs efficiently!
Computer program:
Accepts Input (Data)
Performs a Sequence of action with the input
Generates Output (Data)
Efficient Management of Data
(Data Structures)
Efficient Sequence of Actions
Algorithms
Algorithms
Sequence of actions a ``dumb’’ machine can follow
For j=1 to N
print j
Efficient versus Inefficient algorithm
Design of Algorithms
You have a problem to solve
Design an efficient algorithm
Use good data structures
Show that your algorithm works!
Prove its correctness
Study the efficiency of your algorithm
Formal Study of Algorithms
Design of Algorithms
Proving Correctness of Algorithms
Formal study of efficiency of algorithms
Run time
Storage required
