Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

+ == Algorithms Overview ==
+ === Numeric operations without limit ===
+ 
+ The same algorithm as a calculation with figures written down on paper.[[BR]]
+ For example, 
+ 
+ ~-''a = a,,m,,a,,m-1,,a,,m-2,,a,,m-3,, ... a,,3,,a,,2,,a,,1,,''-~[[BR]]
+ ~-''b = b,,n,,b,,n-1,,b,,n-2,,b,,n-3,, ... b,,3,,b,,2,,b,,1,,''-~
+ 
+ ~-''c,,1,, = a,,9,,a,,8,,a,,7,,a,,6,,a,,5,,a,,4,,a,,3,,a,,2,,a,,1,, + b,,9,,b,,8,,b,,7,,b,,6,,b,,5,,b,,4,,b,,3,,b,,2,,b,,1,,
= a,,1~9,, + b,,1~9,,''-~
+ 
+ if c,,1,, ≥ 1000000000, round up
+ 
+ ~-''a + b = c,,l,,c,,l-1,,c,,l-2,,c,,l-3,, ... c,,3,,c,,2,,c,,1,,''-~

  == Future Plans ==
   * Characterize columnfamily
   * Make the form for distributed algorithms
