A linear non-stationary conflict-interaction problem for controlled objects with n pursuers and m evaders with equal dynamical potency of each participant is considered. The objective of the pursuers is to capture all the evaders; the objective of the evaders is to avoid overtaking of at least one of them. Sufficient conditions for the global evasion problem solvability are stated. 相似文献

The paper studies problems of group pursuit for linear differential games with integral constraints. The problems are analyzed on the basis of Chikrii’s method of resolving functions. The proposed method substantiates the parallel approach strategy, i.e., the Π-strategy. The new sufficient solvability conditions are obtained for problems of group pursuit. As an example, two classes of problems are considered, namely, the Pontryagin control example and a group pursuit with a simple motion for the case of “l-catch.” 相似文献

A general scheme is proposed deriving different types of sufficient conditions for a group pursuit starting from given initial positions to terminate in a finite time. The results are applied to some examples of group pursuit.Translated from Kibernetika, No. 1, pp. 55–62, January–February, 1989. 相似文献

The problem of estimating parameters of a linear regression with allowance for inequality constraints on the parameters is
considered in the special case when its variables have a trend. A parameter estimation algorithm is described. The consistency
of parameter estimates is proved and their asymptotic distribution is found. Consistent estimates are proposed for the mean-square
error matrix of estimates of regression parameters and noise dispersion under rather general assumptions on the law of noise
distribution.

The pursuit of one evader by a group of controlled pursuers is considered for the case of simple motion of the players in nonempty compact sets. Sufficient solvability conditions are derived. These conditions are sometimes also necessary.Translated from Kibernetika i Sistemnyi Analiz, No. 3, pp. 131–137, May–June, 1992. 相似文献

We characterize a nontrivial special case with a polynomial-time algorithm for a well-known parallel machine scheduling problem
with precedence constraints, with a fixed number of machines, and with tasks of unit length. The special case is related to
instances with given maximum path length and maximum degree of the task precedence graph. The method is based on the observation
that the number of tasks is either small and bounded by a constant depending on the maximum path length and maximum degree,
or alternatively, the number of tasks is large, giving a “dense” schedule. 相似文献

The game problem of pursuit is studied for dynamic processes evolving under uncertainty and counteraction. The terminal set is supposed to be a cylindrical set-valued mapping. The method of resolving functions is used to establish the sufficient conditions for the game termination in the class of quasi- and stroboscopic strategies for various schemes of the method. The guaranteed times are compared. The results are illustrated using the model with integral control unit and game problems with simple motion. 相似文献

Consideration is given to a differential game on the plane when the moves of a pursuer and a running away are described by equations of the simple move, and integral constraints are imposed on control functions. In the process of the game the pursuer moves within the prescribed closed convex subset of the plane and the running away moves along its boundary. In the case when the running away has an advantage of resources, the development is made of the runaway strategy that affords the lower bound for the distance between the players. In the case when the pursuer has an advantage of resources, for any initial positions of the players the optimal time of pursuit is found and optimal strategies of the players are set up. 相似文献

The paper deals with time-optimal control of performance of jobs on a single machine. It is assumed that each job is available for processing at the moment which is a positive strictly decreasing continuous function with respect to the amount of a constrained resource (e.g. fuel, raw materials). An algorithm of finding the time-optimal control, i.e. time-optimal permutation of jobs with resource allocation, is presented. 相似文献

Nonnegative large-scale linear programming problems with group constraints are extremely important for different applications in economics, technology, and other spheres. In this paper, we describe a new approach to preprocessing of these problems so that to reduce their dimensions considerably by defining and removing redundant constraints and variables. 相似文献
