....oe of methods which maximizes the probability of achieving the goal by the deadline is straightforward. In the case of an agent faced with multiple goals, even where there is only one method for each goal, optimal choice of a sequence of methods is more difficult. By reducing the knapsack problem [15] to the problem of computing the expected opportunity cost, Etzioni shows that computing the expected opportunity cost of a method is NP complete. 6 The expected opportunity cost of a method is a measure of the benefit that might 6 The knapsack problem involves a set of objects represented by ....
