Sci. (Phys-Math), Acting Associate Professor at Al-Farabi Kazakhstan National University, Almaty, Kazakhstan. The peculiarity of the considered problem is that its constraints contain only linear equations. Unfortunately, the practical application of the method can lead to significant computational problems that narrow the scope of its application [3].
In addition, the method of Lagrange multipliers reduces the solution of the original problem to the search for a saddle point of the Lagrange function. The numerical realization of the method of modified Lagrange functions involves the calculation of second derivatives which are not defined everywhere for many known modified Lagrange functions [4]. The search for a minimum point by the methods of penalty and barrier functions becomes more complicated when the extremum is reached at the boundary of the domain.
A modification of the method of logarithmic barrier functions was proposed, based on the idea of a parametric shift of the constraints of the original problem. As follows from lemma 1, in order to construct admissible solutions of problem (4), it is necessary to solve problem (7), (8) for different values of k and determine such values u,k in which.

- Convergence of the sequence
Then, by convexity criterion for smooth functions on a convex set, function F(u) is convex on U0. It follows from (17), that numerical sequence F un is strictly decreasing and it converges due to the fact that the function F u 0,u,uU0 is bounded below, i.e. If the function F u C1M u0 is convex on the convex set M u0 , then the following inequality holds necessarily and sufficiently.
The next theorem answers the question about the convergence of the given sequence with the solution of the original problem (1), (2). Since the function J u C1,1 U0 is convex on the convex set U0, it is necessary and sufficient to have. Choose an arbitrary element uk of the set U; 4. Construct an auxiliary approach uk U with algorithm 1;.
Further, the linear programming problem is solved by adjusting the value of the objective function on the set of admissible solutions. A justification of the method, a description of the algorithm for solving the auxiliary problem and the basic problem are proposed.

ASYMPTOTICAL ESTIMATE FOR SOLUTIONS OF GENERAL SEPARATED LIMIT PROBLEMS FOR SINGULARLY DISTORTED THIRD-ORDER DIFFERENTIAL EQUATIONS. In this paper we consider a general distributed boundary value problem for linear third-order ordinary differential equations with a small parameter for the two highest derivatives. We study the considered boundary value problem in the case where the additional characteristic equation, together with the zero roots, has roots with negative and positive real parts.
Using introduced initial and boundary functions, an analytical representation of the solution of the perturbed problem was found. The questions about the limiting transition of the solution of the perturbed problem to the solution of the unperturbed problem when the small parameter tends to zero are proved. Keywords: small parameter, asymptotic behavior, singular perturbed problem, unperturbed problem, boundary value problem, phenomenon jump, passage to the limit.

In this article we discuss the construction of plane sections of a polyhedron with planes. Constructing the intersection of a polyhedron with a plane is a way of constructing lines that are traces of the intersection of the faces of the polyhedron with a given plane. The cutting plane is defined as follows: by three points that do not lie on the same line;.
Parallelism, perpendicularity of dihedral angles are used, triangles of any parallelogram serve as an image of these triangles and a parallelogram. The image of a tetrahedron is an arbitrary convex or non-convex square with diagonals carried within it. Keywords: image of spatial figures, trace, cut, correspondence, trace of a cut, belong, association, crossing of figures.

NUMERICAL ALGORITHM OF THE CONTAINED SOLUTION FOR THE INVERSE PROBLEM RECOVERY OF THE BOUNDARIES OF INHOMOGENITY. 1Candidate of physical-mathematical sciences, professor Professor of the International Kazakh-Turkish University named after Khoja Ahmed Yasawi, Turkestan, Kazakhstan.
The paper deals with the construction of a numerical algorithm for the approximate solution of the inverse determination of the inhomogeneity limit. In deriving the equations, a transition from a Cartesian coordinate system to a spherical coordinate system is used. With the help of a special Maple program we built the graphical representation of multisoliton solutions, we can see that the collision of the soliton preserves the saving form.

In teaching electronic theory, we were applied, the discoveries of great scientists of the 19th and 20th centuries. The application of electronic theory to explain the electric current in different environments: metals, semiconductors, liquids, gases and in vacuum given in the form of a table. The wave process caused by applying an external dynamic load to the points of the front boundary of a rectangular strip, which amounts to setting the mixing velocity vector at this boundary.
Formulated in terms of stresses and velocities, the mixed problem is modeled numerically using an explicit difference scheme for the count-through, based on the method of spatial characteristics. At special corner points of a rectangular hole, where the first and second derivatives of the unknown functions suffer from a discontinuity of the first kind, computed finite difference relations are obtained to find the required functions. The concentration of dynamic stresses near the corner points of a rectangular hole is studied.

The dependence of the reaction force of the vibration fixed body on the disturbance force is constructed and it is shown that the dynamic coefficient is much less than unity, so the considered vibration protection system is also effective for periodic pulsed action.
