Centralised training and decentralised execution (CTDE) is one of the most effective approaches in multiagent reinforcement learning (MARL). However, these CTDE methods still require large amounts interaction with environment, even to reach same performance as very simple heuristic-based algorithms. Although modelbased RL a prominent approach improve sample efficiency, its adaptation multi-agen...

A novel BRST quantization is described, which is applied in generalizing the JackiwNair construction of anyon. We have explicitly shown that the matter states connected to an unconventional ("non-zero") BRST ghost sector are physical. They are identi ed to the Jackiw-Nair system in a particular gauge. Also for the rst time an indepth analysis of the present kind for a reducible constraint syste...

We study a 3D bicrystal containing an axially symmetric shrinking grain which is initially a spherical segment attached along a circular groove root to the flat exterior surface of the second grain. Following Mullins [1]-[3], a time dependent problem is formulated for the coupled motion of the grain boundary, the groove root, and the external surface. Numerical solutions calculated using an imp...

We investigate the problem of learning the control of small groups of units in combat situations in Real Time Strategy (RTS) games. AI systems may acquire such skills by observing and learning from expert players, or other AI systems performing those tasks. However, access to training data may be limited, and representations based on metric information – position, velocity, orientation etc. – m...

In general bosonic closed string backgrounds the ghost-dilaton is not the only state in the semi-relative BRST cohomology that can change the dimensionless string coupling. This fact is used to establish complete dilaton theorems in closed string field theory. The ghost-dilaton, however, is the crucial state: for backgrounds where it becomes BRST trivial we prove that the string coupling become...

Korvas P, Musil R, Došla J, Kolářová K, Pavlík J, Šenkýř J. The study of vertical ground reaction during walk of Czech women. J. Hum. Sport Exerc. Vol. 8, No. Proc2, pp. S54-S60, 2013. The aim of this study was to find whether it is possible to explain different plantar loading during absorption and propulsive stages of stance in the observed persons by means of basic body indicators or time ch...

With modern video games frequently featuring sophisticated and realistic environments, the need for smart and comprehensive agents that understand the various aspects of complex environments is pressing. Since video game AI is often specifically designed for each game, video game AI tools currently focus on allowing video game developers to quickly and efficiently create specific AI. One issue ...

We study the hierarchy of hidden space-time symmetries of noncritical strings in RNS formalism, realized nonlinearly. Under these symmetry transformations the variation of the matter part of the RNS action is cancelled by that of the ghost part. These symmetries, referred to as the α-symmetries, are induced by special space-time generators, violating the equivalence of ghost pictures. We classi...

The objective of this study was to evaluate the effect of HMB on selected parameters of the humoral immunity in calves. The experiment was performed on 14 calves aged 30 ± 2 days, divided into two equal groups of control (group K) and experimental (group H) animals. The feed administered to the experimental calves was supplemented with HMB at 40 mg/kg BW, whereas the control calves were adminis...

Data on Live Births (LBs) and Fetal Deaths (FDs) were obtained from vital statistic records maintained by the Statistics and Information Department, Ministry of Health, Labour and Welfare (Tokyo, Japan) for the years 1995-2008. These data cover the entire Japanese population. LB certificates contain information on nationality, sex, date of birth, BW, GA, parental dates of birth and age, single ...
