What is the difference between a heuristic and an algorithm?
2010年2月25日 · An algorithm is the description of an automated solution to a problem. What the algorithm does is precisely defined. The solution could or could not be the best possible one but you know from the start what kind of result you will get. You implement the algorithm using some programming language to get (a part of) a program.
algorithm - Finding anagrams for a given word - Stack Overflow
2017年4月27日 · Example algorithm: Open dictionary Create empty hashmap H For each word in dictionary: Create a key that is the word's letters sorted alphabetically (and forced to one case) Add the word to the list of words accessed by the hash key in …
algorithm - Finding all possible combinations of numbers to reach …
2011年1月8日 · Here is a Java version which is well suited for small N and very large target sum, when complexity O(t*N) (the dynamic solution) is greater than the exponential algorithm. My version uses a meet in the middle attack, along with a little bit shifting in order to reduce the complexity from the classic naive O(n*2^n) to O(2^(n/2)) .
algorithm - how do I create a line of arbitrary thickness using ...
Here is a paper and Delphi implementation of a modified version of Bresenham's algorithm for drawing thickened lines. You may also want to take a look at Anti-Grain Geometry , a library for high-quality and high-performance software rendering of 2D graphics.
What is the difference between an algorithm and a function?
An Algorithm usually refers to the method or process used to end up with the result after mathematical processing. A Function is a subroutine used to avoid writing the same code over and over again. They are different in their uses. For instance, there may be an Algorithm that is used for encrypting data, and a function for posting code to a ...
algorithm - What does O (log n) mean exactly? - Stack Overflow
2010年2月22日 · Algorithm 1: Algorithm 1 prints hello once and it doesn't depend on n, so it will always run in constant time, so it is O(1). print "hello"; Algorithm 2: Algorithm 2 prints hello 3 times, however it does not depend on an input size. Even as n grows, this algorithm will always only print hello 3 times.
Algorithm to return all combinations of k elements from n
2008年9月24日 · doc_180: Chase's algorithm is more complicated than the other algorithms but has the added benefit that each successive combination differs from the previous by just one element. This can be useful if the work that needs to be performed on each combination can be made faster if using the partial work of the previous combination.
algorithm - Finding the highest 2 numbers- computer science
2012年9月21日 · The algorithm I gave takes exactly n+log(n)-2 comparisons (not just asymptotically). Note that the measure in question is the number of comparisons, not running time. (But n+log(n) is O(n), so running time is O(n) too.)

I am trying to connect to remote sftp server over ssh with JSch (0.1.44-1) but during session.connect(); I am getting this exception: com.jcraft.jsch.JSchException: Algorithm negotiation fail at com.
algorithm - How is pi (π) calculated? - Stack Overflow
2016年10月29日 · I believe the algorithm you're looking for is what's known as a "Spigot Algorithm." One particular kind is the BBP (Bailey-Borwein-Plouffe) formula. I believe that's what you're looking for.
