INTSOLVER: An interval based solver for Global Optimization

from INTSOLVER: An interval based solver for Global Optimization by Tiago Montanher
Interval based functions to solve small global optimization problems with guaranteed bounds.

silevy(type, n)
function inidata = silevy(type, n)
% Levy's problem initial data.
% Set type equal 0 to get double initial data.
% Set type equal 1 to get interval initial data.
% Set the number of variables with n.

  if type == 0
   inidata = ones(1,n) * 5;
  end
  
  if type == 1
   inidata = ones(1,n) *infsup(-10,10);
  end
end
