% OBJECTIVE FUNCTION
f = @(x) [(x(:,1)-2).^2 + (x(:,2)-1).^2 + 2,...
       9*x(:,1) - (x(:,2)-1).^2]

% OPTIMIZATION SETTINGS
o = struct	% initializing struct 
g1 = @(x) 225 - sum(x.^2,2)
g2 = @(x) 10 - x(:,1) + 3*x(:,2)
o.g = @(x) g1(x).*(g1(x)<0) + g2(x).*(g2(x)<0)	% constraints
o.d = 2	% dimension of decision variable
o.lb = -20	% lower bounds
o.ub = 20	% upper bounds

% ALGORITHM OPTIONS

o.maxit = 40	% number of iterations 
o.pop = 40	% number of population 

% OPTIMIZATION 
rng(0)	% for tractability 
[popPos,popFront,popCost,popInfo,traceIt] = nsga2(f,o)	% running minimization  

% ANIMATION
% Uncomment the following code to generate animation % 
% rng(0)
% [~,~,~,~,~,info] = nsga2(f,o)
% info.plot = 'pareto'
% info.animate = true	% plot animation 
% info.animfreq = 2	% frame frequency 
% optimview('nsga2',info)
