In this paper we consider the problem of minimizing
$$\bar{I}\left[ y \right]: = \int\limits_{a}^{b} {\bar{f}} \left( {x,y\left( x \right),y'\left( x \right)} \right)dx$$
(1)
in the set \(ar A\) of absolutely continuous functions y(·): [a, b] → ℝ satisfying the end conditions
$$y(a) = lpha ,y(b) = 0,$$
(2)
where α is a prescribed constant. In (1), [a, b] is a bounded interval, “′ ” denotes differentiation with respect to x, and the integrand \(ar f = ar f(x,y,p)\) is assumed to be smooth (C 3) and nonnegative. In addition, \(ar f\) is assumed to satisfy:
$${ar f_{pp}} eqslant 0.$$
