Searches follow that same probe sequence, and are considered unsuccessful as soon as they hit an empty location. 2-8 General Concepts and Techniques The simplest way to generate the probe sequence is by first evaluating the hash function, and then scanning the table sequentially from that location (and wrapping around the end of the table). This is called linear probing, and is reasonably efficient if the load factor is not too high, but, as the table becomes full, it is too slow to be practical: 1 1 1 1+ +Θ 2 1−α m 1 1 1 ESn = 1+ +Θ 2 (1 − α)2 m EUn = Note that these formulae break √ down for α = 1.

Jk ), we reduce the time required to Θ(n2 2n ), still exponential, but considerably less than without caching. 5 Greedy Heuristics Optimization problems always have an objective function to be minimized or maximized, but it is not often clear what steps to take to reach the optimum value. 4, we used dynamic programming to examine systematically all possible trees; but perhaps there is a simple rule that leads directly to the best tree—say by choosing the largest βi to be the root and then continuing recursively.

2, is called merge sort. Let T(n) be the time required by merge sort for sorting n values. The time needed to do the merging is proportional to the number of elements being merged, so that T(n) = cn + 2T (n/2) , because we must sort the two halves (time T(n/2) for each half) and then merge (time proportional to n). 2 that the growth rate of T(n) is Θ(n log n), since u = v = 2 and g(n) = Θ(n). 2 Schematic description of merge sort. 4 Dynamic Programming In the design of algorithms to solve optimization problems, we need to make the optimal (lowest cost, highest value, shortest distance, and so on) choice among a large number of alternative solutions; dynamic programming is an organized way to find an optimal solution by systematically exploring all possibilities without unnecessary repetition.
