% Setup a clean YALMIP environment 
yalmip('clear') 

% Define all variables 
x1 = sdpvar(1);
x2 = sdpvar(1);

% Define objective function 
objective = -(-(power(x2,2)-7*x2)+12*x1+0-(0));

% Define constraints 
F = set([]);
F=[F,-2*power(x1,4)-x2==-2];
F=[F,0<=x1<=2];
F=[F,0<=x2<=3];

% Solve problem
sol = solvesdp(F,objective,sdpsettings('solver','bmibnb','allownonconvex',1));
