ABSTRACT: The authors analyze some behavior problems for variable -structure stochastic
automatons in game situations. The definitions and notation adopted in the paper are those of
M. L. Tsetlin (e.g., Konechnyye avtomaty I modelfrovanlye prosteyshikh form povedenkya.
--UMN, 1963, vol. XVIII, vyp. 4 (112)). The 2;ero-sum game of a variable -structure auto-
maton with a single opponent using one pure strategy Is considered In an effort to demonstrate
the conditions for asymptotic behavior optimality of such an automatic device in a stationary
random environment. The simplest stochastic automaton version is considered, i.e., the line

automaton without input. Expressions are derived for the mathematical win expectancy of such
an automaton (Ck). Games by t~o such Ck automatons are considered for pure strategies,
state diagrams are analyzed, and experimental data on Ck automaton assignment game behaviol
are presented. In the case of the nonstationary (random) environments (to which the problem
of inter-automaton gaming can ultimately be resolved) it Is not yet possible to formulate re-
quIrcments as the method of changing the state transitioif probabilities. It Is also shown that
a Ck automaton which has functioned for any extended period of time in one stationary medium
is very slow to retrain itself for operation in another environment. The elimination of this
defect is seen as the k~y to the design of an automaton capable of optimal behavior in nonsta-
tionary environments. The authors wish, in conclusion, to expres..i their sincere gratitude to
M. L. Tgetlin, I. I. aaktskly-Shapi o, V. Yu. Krylov. S. L. GInzburg, and V. A.Volk
for their willingness to take part in a discussion of the problems considered In this paper and

TITLE: The Flotability of Gypsum and of a Precipitate With Different
Reagents

ABSTRACT: The authors investigated various enrichment reagante and reg-
ulators for the flotation or gypsum (CaSO 4' 2H20) and the
precipitate (CaHF0 4' 2H20) to achieve a separation of the two
substances by flotation. The investigations carried out showed
the following results: in the presence of oleic acid (consump-
tion.'750-1000 g/ton) and of IM-11 (consumption: 500-750 g/ton)
the precipitate and gypsum were practically completely floated
at pH 6-5-7. The flotability of the precipitate and gypsum by
oleic acid decreases rapidly with the decrease of the pH value
of the pulp. In the flotation with IM-11 a decrease of the p'[
value leads to a certain activation of the gypsum flotation
and to a considerable reduction of the flotation of the pre-
Card 1/4 cipitate. Thepe effects of the pH value are shown by fil-ure 2.

SOV/153-2-3-20/29
The Flotability of Gypsum and of a Precipitate With Different aeagents
The anion reagent aeroflot-25 proved to be the most efficient
among the flotation reagents investigated. In the presence of
aeroflot-25 the precipitate is strongly floated whereas gypsum
is hardly floated at all. The flotation of a precipitate-
gypsum mixture differs from the flotation of the individual
components since in the common presence of gypsum and pre-
cipitate in the liquid phase of the pulp a mutual inhibition
of the flotability occurs. It was found that a reduction of the
content of precipitate in the mixture leads to a considerable
reduction of the flotation which is due to the inhibiting ef-
fect of gypsum on the flotation of the precipitate. The use of
aeroflot-25 in the mixture with kerosene as collector for the
basic flotation-in the presence of copper salts and the pro-
cessing of the residues with reagent IM-11 in the presence of
trikresyl phosphate makes it possible to obtain a concentrate
containing 29-3(YA P205from the original mixture with a content
of approximately 17% P20 5* In this case 79-80~ of P205 are
again obtained. Purthermore it was found that the use of tri.-
