Consider the greedy algorithm for the bin-packing problem, which is called the best-fit algorithm: place each item into the bin that is the best fit, that is, the bin that has the least capacity remaining (but still has enough room to fit the weight). If it does not fit in any bin, then start a new bin. Apply best-fit algorithm to the instance: s1 = 0.4, s2 = 0.7, s3 = 0.2, s4= 0.1, s5 = 0.5, capacity = 1.
