The present study is an attempt to obtain information on the behavior of lymphocytes in guinea pigs with eczematous hypersensitivity when the lymphocytes are brought into contact with antigen in vitro. Unexpectedly, it was observed that some of the peripheral lymphocytes of 2 ,4-dinitro-1-chlorobenzene (DNCB) sensitized guinea pigs lyse "spontaneously" in vitro, and that the lysis is inhibited ...

In this paper, an efficient modified nonlinear conjugate gradient method for solving unconstrained optimization problems is proposed. An attractive property of the modified method is that the generated direction in each step is always descending without any line search. The global convergence result of the modified method is established under the general Wolfe line search condition. Numerical r...

New accelerated nonlinear conjugate gradient algorithms which are mainly modifications of the Dai and Yuan’s for unconstrained optimization are proposed. Using the exact line search, the algorithm reduces to the Dai and Yuan conjugate gradient computational scheme. For inexact line search the algorithm satisfies the sufficient descent condition. Since the step lengths in conjugate gradient algo...

Optimality functions pioneered by E. Polak characterize stationary points, quantify the degree with which a point fails to be stationary, and play central roles in algorithm development. For optimization problems requiring approximations, optimality functions can be used to ensure consistency in approximations, with the consequence that optimal and stationary points of the approximate problems ...
