$\sqrt{3x-1}+(1+x)^2$

$e^x = \sum_{i = 0}^\infty \frac{1}{i!}x^i$

Constraints are
   - $3x_1 + 6x_2 + x_3 =< 28$
   - $7x_1 + 3x_2 + 2x_3 =< 37$
   - $4x_1 + 5x_2 + 2x_3 =< 19$
   - $x_1,x_2,x_3 >=0 $

The trial vector is calculated as follows:
- $u_i(t) = x_i(t) + \beta(\hat{x}(t) − x_i(t)) + \beta \sum_{k = 1}^{n_v}(x_{i1,k}(t) − x_{i2,k}(t))$
$f(x_1, x_2) = 20 + e - 20exp(-0.2 \sqrt {\frac {1}{n} (x_1^2 + x_2^2)}) - exp (\frac {1}{n}(cos(2\pi x_1) + cos(2\pi x_2))$
