Eve Algorithms

We try to find new ways to improve performance, by using a better logic. Our strive is to create efficient software based on reduced complexity and sufficiency.

Precision

We believe, specific algorithms can be improved if we consider precision sufficient and avoid wasting time by computing high precision when it is not necessary.

Example:

Next sqrt() function has a precision parameter. If the precision is specified the number of iteration is considerable reduced. We can also have higher precision than usual.


# function with precision
driver test_sqrt:

** overwrite default precision
   set $epsilon  = 1^-2;

** extract square root with precision
function sqrt(x: f64, p = $epsilon  :f32) => (z = 1.0 :f64):
  loop
    let z -= (z * z - x) / (2 * z); 
  repeat if (z * z - x) > p;
return;

process
  ** test with different precision
  print sqrt(10,1^-3);   --  3.1624556228038903
  print sqrt(10,1^-10);  --  3.16227766017
  print sqrt(10,1^-14);  --  3.162277660168379 
return;
