Live Long There and Prosper: How Internal Migration from Small Towns Works

More than half of school graduates in medium-sized Russian cities will change their place of residence either forever or at least for a long time. According a report on internal migration presented by HSE demographers at the XX April International Academic Conference, these people are lost to their cities.

A Modification of Dynamic Programming Algorithms to Reduce the Running Time or/and Complexity
Gafarov E., Lazarev A. A., Werner F. Otto-von-Guericke Universitaet, 2010. No. 20.
In this paper, we present a modification of dynamic programming algorithms (DPA), which we denote as graphical algorithms (GrA). For the knapsack problem and some single machine scheduling problems, it is shown that the time complexity of the GrA is less that the time complexity of the standard DPA. Moreover, the average running time of the GrA is often essentially smaller. A GrA can also solve largescale instances and instances, where the parameters are not integer. In addition, for some problems, GrA has a polynomial time complexity in contrast to a pseudo-polynomial complexity of DPA.

Свойства оптимальных расписаний задачи теории расписаний минимизации суммарного взвешенного момента окончания для одного прибора
Лазарев А. А., Кварацхелия А. Г. Автоматика и телемеханика. 2010. № 10. С. 80-89.

In this paper, we consider the minimizing total weighted completion time in preemptive equal-length job with release dates scheduling problem on a single machine. This problem is known to be open. Here, we give some properties of optimal schedules for the problem and its special cases.

Гинтова М. А., Костырко А. А., Плаксин С. М. и др. Вопросы государственного и муниципального управления. 2012. № 1. С. 7-25.

In this paper the authors analyze the optimization of public service delivery in Russia. The role of the optimization of administrative processes in the modernization of public administration is also considered; major activities aimed at the optimization of the public services delivery in 2010-2011 are described; some background information for decision making process is revealed; major methods of improving quality and accessibility of public services are analyzed; the key methodological approaches for the reengineering of public services and spheres of government regulations are presented. Basing on the researches conducted, the authors propose the ways of making the activities aimed at the optimization of public services effi cient.
