WebAlgorithm #1: order the jobs by decreasing value of ( P [i] - T [i] ) Algorithm #2: order the jobs by decreasing value of ( P [i] / T [i] ) For simplicity we are assuming that there are no ties. Now you have two algorithms and at least one of them is wrong. Rule out the algorithm that does not do the right thing. Greedy algorithms have a long history of study in combinatorial optimization and theoretical computer science. Greedy heuristics are known to produce suboptimal results on many problems, and so natural questions are: • For which problems do greedy algorithms perform optimally? • For which problems do greedy algorithms guarantee an approximately optimal solution?
