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

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

% Define objective function 
objective = -(-(-sqr(x1)-4*sqr(x2))+0-(0));

% Define constraints 
F = set([]);
F=[F,x1+x2<=10];
F=[F,x1+5*x2<=22];
F=[F,-3*x1+2*x2<=2];
F=[F,-x1-4*x2<=-4];
F=[F,x1-2*x2<=4];
F=[F,0<=x1];
F=[F,0<=x2];

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