基于微分的多目标优化问题

function ind = randompoint(prob, n)
%RANDOMNEW to generate n new point randomly from the mop problem given.

if (nargin==1)
    n=1;
end

lowend = prob.domain(:,1);
span = prob.domain(:,2)-lowend;
point = randarray.*(span(:,ones(1, n)))+ lowend(:,ones(1,n));

indiv = struct('parameter',[],'objective',[], 'estimation', []);
ind = repmat(indiv, 1, n);
[ind.parameter] = cellpoints{:};

% estimation = struct('obj', NaN ,'std', NaN);
% [ind.estimation] = deal(repmat(estimation, prob.od, 1));
