http://www.palfrader.org/hashing/

Extractions: home Hashing V 0.1 Hashing is a method to store data in an array so that storing, searching, inserting and deleting data is fast (in theory it's O(1)). For this every record needs an unique key. The basic idea is not to search for the correct position of a record with comparisons but to compute the position within the array. The function that returns the position is called the 'hash function' and the array is called a 'hash table'. In our examples our key is an integer value as is the actual data. [note that I use pascal syntax since this is easily readable by everybody I asume] type record key integer data integer end the hash table now looks like this: const type array of If we know that the key is in a small range we could use the key itself as an index (also called hash address) for our array. However this is very rarely the case so we have to find some kind of hash function. A very common and not so bad function is a simple MODulo function: function key integer integer begin key MOD end If we now want to insert a record into the hash we could do it this way: procedure VAR hash rec begin hash rec key rec end But wait! What happens if two different keys return the same hash address from the hash function? Well if you have a good hash function this happens very rarely but it can and will happen. There are two ways to handle a so called 'hash collision'.

We are The Hash House Harriers, a loosely knit international group with chapters in every major U.S. city and 164 countries around the world. A typical trail ride (Bash) involves two members (Hares) leaving the pre-arranged meeting point with a ten minute lead, using flour thrown from a backpack the two mark a trail through woods, tracks and bike trails for the 'pack' to follow in an effort to catch them before they reach the ending spot where the beer is hidden!! To get there you have to follow the trail the 'hares' have marked, the whole concept is based on the old English game of "Hare and Hounds". The trail is typically 10-15 miles in length and covers a wide variety of terrain. A Mountain Bike is preferred!
Felgall - What Is Hashing?
What is hashing? What is collision and what are the differences between double hashing,chaining, bucket addressing, perfect hashing, and dynamic hashing?
http://members.blue.net.au/felgall/hash.htm

Extractions: Site Map What is Hashing? Question: I want to know about direct addressing, dictionary lookup, and indirect addressing. Can you explain about division remainder, digit analysis/extraction, folding, mid-square, and radix conversion? What is collision and what are the differences between double hashing, chaining, bucket addressing, perfect hashing, and dynamic hashing? What is linear probing and what are synonyms? anonymous Answer: Hash tables are one of the most efficient means of searching for data. A hash table establishes a mapping between all of the possible keys and the position where the data associated with those keys is stored. I don't know exactly how all of the hashing methods that you are asking about work but the following should go at least partway towards answering your questions. Direct Addressing is where the hashing algorithm guarantees that no two keys will generate the exact same hash value. This is the ideal situation but is impractical in most situations. Instead most hash functions map multiple keys to the same has value and provide indirect addressing mechanisms to handle the situation where two keys map to the same value. The situation where this occurs is called a

The fraternity received its name from the Selangor Club Chambers, which due to it's lackluster food was commonly referred to as the ‘Hash House'.

Discovered early on in computer science, they are among the most approachable algorithms and certainly the most enjoyable to tinker with. Moreover, the endless search for the Holy Grail, a perfect hash function for a given data set, still consumes considerable ink in each year's batch of computer-science journals. For developers who program for a living, however, recondite refinements to unusual hashing functions are of little use. In general, when you need a hash table, you want a quick, convenient hashing function. And unless you know where to get one, you will almost certainly fall prey to the fallacy that you can write and optimize one quickly for your particular application.

Extractions: Hash History Hash Glossary Hashing: A social event with two parts: the trail and the drinking, singing and laughing after the trail. The Trail A trail leads the pack (you and everyone else who did not lay the trail) through forests, along city streets, over rivers, inside buildings, etc. Trails are typically 3-6 miles long, and usually take less than two hours to complete. The hares (the person or people who did lay the trail) use chalk, flour, or toilet paper to mark where the trial goes. Along the way, the you will discover decision points , places where the trail goes in many directions. The goal of the pack is to find the true trail that will lead them to the finish, which might be at or near the start, or it might be miles away. A full description of markings is available. The Drinking, Singing, and Laughing After you have finished the trail, you will either end up at a bar, or find a cooler or keg in the woods or at someone's house. Either way, the hares should have one of your favorite beverages, such as beer, soda, or water. Feel free to drink as much as you want, but save some room for the down-downs Down-downs are a form of ritualized drinking. When you have a cup, can, or bottle of the beverage of your choice, the pack will sing a song with the words ``drink" or ``down" in it. At that point, you should start drinking. You will continue drinking until one of two things happen:

Extractions: Now at that time the RA was a ranting Scotsman whose Hashname (everyone ends up with a hashname) was 'Elephant Man'. Nobody every asked him why he was called that because nobody could ever understand his broad Scots accent. In fact people were often called out and punished, who left the Circle afterwards having no idea of their crime... The rewards were always a soft drink downed quickly (as Saudi was supposed to be a booze-free) but punishments were something else. Those denounced as bad hashers were herded into the middle, a song sung to them, and then had bucketfuls of water/ flour/ food-colouring thrown at them. There was no time to wash it off as the Hash Horn immediately called for the start of each run, so the 'guilty' ran in their technicolour outfits! Luckily the temperature was always warm to very hot, so nobody minded too much, but the flour in the mixture did seem to start 'cooking' on a hot day.... Another year, another contract extension, and I was now 'On-Sec' (sic) for the Hash as the 'Old Guard' kept departing. I attended my first InterGulf Hash in Dubai, and then my first World InterHash in Bali - great!!! Then when the current GM, Dave 'Timbertool' Woodcock, announced he was being sent elsewhere, I eventually became Joint Master with Jim 'Startkers' Stark, and then Jim 'Mooseburger' Mace, before doing the whole lot as GM on their departure. Before long we had sponsors filling hash coffers and a good, strong Poliburo of 20 plus. As in any organisation, these people were the responsible for the success or failure, and the character of the Hash.
