Hello everyone,I am java programmer.I am developing several applications in Swings and other frameworks.I am good in OOPS and most of the Core Java concepts.Currently developing websites in JSP and PHP.But one day i was asked to write an algorithm for fibonacci numbers generation which took more than 10 minutes to write for me(and its wrong...

Hi, I am planning to use Nearest Neighbor algorithm for predicting the user behavior. Basically, I have a large number of reviews along with their star ratings(1-5). For a new user that registers with my system, I want to show him the best matched results when that new user searches for an item. For example, UserA and UserB have rated three...

what is the name of the game which 2 players complete the squares on paper? i am interested in its algorithm but first i have to get some information about it.

HI frdz, can any one tel me to find out da complexity of a given algorithms. I dont know about notations. when im reading notations im not getting anything,totally confusing. Hope i can get help!

Hi...................... I want to get the following pic table set in ms excel which is actually i had formed in Ms Word, but there is problem with it calculating the values automatically. So i have decided to make this sheet in excel, but I dont know the formula to put into the last two cell to automatically calculate the same result. I have...

Hi! I have some binary data stream which passes geo location coordinates - latitude and longitude. I need to find the method they are encoded. 4adac812 = 74°26.2851' = 74.438085 2b6059f9 = 43°0.2763' = 43.004605 4adaee12 = 74°26.3003' = 74.438338 2a3c8df9 = 42°56.3177' = 42.938628

if I have while loop like this while(1>i/x) and i-- and x++ and initait value for x=10 and i=n my question is when I want to know value of x what i have to do . i want general idea to solve this Que x=10,i=n while (1>=i/x) {i=i-1; x=x+1} print x

I have a system that generates a 24ch alpha-numeric string as a tracking number. An example looks like this - 1898240001631501AKL003HS. This is great for what it does (there is information embedded in that string that tells me stuff that I need to know). However, when a customer tries to use an IVR or web site to self service (a tracking...

Hi All, I want to try my hands in AI (artificial intelligence) based application developement. So i just wanted to ask how would we recognise the pattern among the audio and/or graphics files. Hint: application must be capable of sorting all the images of a particular person. Or the audio player must be capable of suggesting some songs to...

Hi, I need a regular expression for capturing the first alpha string in a document not necessarily on the first line match first instance Here is a few tried permutations *

Does anybody give me suggestions in implementing an algorithm using a programming language such as C#. For example, lets say; I had a stream of data continuously coming to me. I want to filter the data based on certain conditions such as "if new data is lessthan 10", discard the new data. I can implement the same by 'C# generic collection',...

I am trying to reduce my data entry workload through automation of an accurate mass calculator. I have a table of accurate "mass to charge" output vs. intensity from an agilent mass spectrometer. Currently I have to key input each of these molecular weights into the "Agilent MassHunter" mass calculator and get the multiple molecular formula...

hi, i am research student, my research topic is about to compare the crawling process for Bfs and Dfs, have anyone willing to share their sample crawler code? Thank You!

In a binary search, with an even amount of numbers, will the algorithm choose the higher or lower middle number? So if the array is: 15 18 18 21 26 31 36 38 Then will it start by looking at 21 or 26?

Hey everyone, I'm planning to implement a dictionary on C#. I have about 30,000 words in my database( i keep them in access database right now. Maybe we can make a decision about which database it should be. ) a word and a definition may contain from 1 to 25-30 chars. The search should work like that ; when user types a, the app should...

Hi everyone, I have a general and a specific question. I never took a mathematical algorithm and converted it to source, so where would I start? The specific question is that I have this algorithm: (attachment) How would i convert this algorithm to source or how would I start? I know it's broken down into a product of an integral...

Im trying to do a regular expression that only gets letters in a certain character set '^+$ but i want to not get words like badd or cabb and only cab or bad so that each character in the character set is only used once or the number of time used in that character set? i dont know if this will be possible because i may have multiple occurences of...

Which method is better and more efficient than the other, to choose a pivot randomly or to choose it by selecting three indexes (index 0, index n/2 and index n) and taking the middlemost number between the three?

Hi, Hoping someone can help. I'm developing a game related to Maths (I'm rubbish personally) and I need to break down the difficulty levels. In my head, I have 6 different levels/descriptions: - Easy (Kindergarten/Elementary) - Medium (Middle school) - Hard (High school) - Expert (Post-secondary education)

Hi, I have got problem with this task. (It's not homework!). We have undirected graph with wages X,Y. Firstly all edges has got X. But if exist path that costs 2X (from vi to vj and (vi and vj arent connected directly)) than we can replace it by Y. Our task is to find minimal distance to all vertex from start vertex. I will write an...
