Abstract: The general discussion of the data flow algorithmic models, and the linear programming problem with
the variating by data flow criterion function coefficients are presented. The general problem is widely known in
different names  data streams, incremental and online algorithms, etc. The more studied algorithmic models
include mathematical statistics and clustering, histograms and wavelets, sorting, set cover, and others. Linear
programming model is an addition to this list. Large theoretical knowledge exists in this as the simplex algorithm
and as interior point methods but the flow analysis requires another interpretation of optimal plans and plan
transition with variate coefficients. An approximate model is devised which predicts the boundary stability point for
the current optimal plan. This is valuable preparatory information of applications, moreover when a parallel
computational facility is supposed.

degree in that this property occurs, was considered. This paper takes up again these subjects, and firstly we
study if there exists some connection between the two first notions. After that, taking into account that selfcontradiction
of a fuzzy set could be understood as the contradiction with itself, and starting from the degrees of
contradiction between two fuzzy sets proposed in 5, we obtain degrees of selfcontradiction. Finally,
preservation of some intuitive properties both in the use of connectives and in the obtaining of new knowledge

A GEOMETRICAL INTERPRETATION TO DEFINE CONTRADICTION

Rating:
(1.00/10)

Abstract: For inference purposes in both classical and fuzzy logic, neither the information itself should be
contradictory, nor should any of the items of available information contradict each other. In order to avoid these
troubles in fuzzy logic, a study about contradiction was initiated by Trillas et al. in 5 and 6. They introduced the
concepts of both selfcontradictory fuzzy set and contradiction between two fuzzy sets. Moreover, the need to
study not only contradiction but also the degree of such contradiction is pointed out in 1 and 2, suggesting
some measures for this purpose. Nevertheless, contradiction could have been measured in some other way. This
paper focuses on the study of contradiction between two fuzzy sets dealing with the problem from a geometrical
point of view that allow us to find out new ways to measure the contradiction degree. To do this, the two fuzzy
sets are interpreted as a subset of the unit square, and the so called contradiction region is determined. Specially
we tackle the case in which both sets represent a curve in 0,12. This new geometrical approach allows us to
obtain different functions to measure contradiction throughout distances. Moreover, some properties of these
contradiction measure functions are established and, in some particular case, the relations among these different
functions are obtained.

Abstract: Nonpreemptive twomachine flowshop scheduling problem with uncertain processing times of n jobs
is studied. In an uncertain version of a scheduling problem, there may not exist a unique schedule that remains
optimal for all possible realizations of the job processing times. We find necessary and sufficient conditions
(Theorem 1) when there exists a dominant permutation that is optimal for all possible realizations of the job
processing times. Our computational studies show the percentage of the problems solvable under these
conditions for the cases of randomly generated instances with n ≤100 . We also show how to use additional
information about the processing times of the completed jobs during optimal realization of a schedule (Theorems
2 – 4). Computational studies for randomly generated instances with n ≤ 50 show the percentage of the twomachine
flowshop scheduling problems solvable under the sufficient conditions given in Theorems 2 – 4.

Abstract: Two assembly line balancing problems are addressed. The first problem (called SALBP1) is to
minimize number of linearly ordered stations for processing n partially ordered operations V = {1, 2, ..., n} within
the fixed cycle time c. The second problem (called SALBP2) is to minimize cycle time for processing partially
ordered operations V on the fixed set of m linearly ordered stations. The processing time ti of each operation
i ∈V is known before solving problems SALBP1 and SALBP2. However, during the life cycle of the assembly
line the values ti are definitely fixed only for the subset of automated operations V\V~ . Another subset V~ ⊆V
includes manual operations, for which it is impossible to fix exact processing times during the whole life cycle of
the assembly line. If j ∈V~, then operation times tj can differ for different cycles of the production process. For the
optimal line balance b of the assembly line with operation times t1, t2, …, tn, we investigate stability of its optimality
with respect to possible variations of the processing times tj of the manual operations j ∈V~.

Abstract: We propose the adaptive algorithm for solving a set of similar scheduling problems using learning
technology. It is devised to combine the merits of an exact algorithm based on the mixed graph model and
heuristics oriented on the realworld scheduling problems. The former may ensure high quality of the solution by
means of an implicit exhausting enumeration of the feasible schedules. The latter may be developed for certain
type of problems using their peculiarities. The main idea of the learning technology is to produce effective (in
performance measure) and efficient (in computational time) heuristics by adapting local decisions for the
scheduling problems under consideration. Adaptation is realized at the stage of learning while solving a set of
sample scheduling problems using a branchandbound algorithm and structuring knowledge using pattern
recognition apparatus.

STATIC ANALYSIS OF USEFULNESS STATES IN TRANSITION P SYSTEMS

(1.00/10)

Abstract: Transition P Systems are a parallel and distributed computational model based on the notion of the
cellular membrane structure. Each membrane determines a region that encloses a multiset of objects and
evolution rules. Transition P Systems evolve through transitions between two consecutive configurations that are
determined by the membrane structure and multisets present inside membranes. Moreover, transitions between
two consecutive configurations are provided by an exhaustive nondeterministic and parallel application of
evolution rules. But, to establish the rules to be applied, it is required the previous calculation of useful, applicable
and active rules. Hence, computation of useful evolution rules is critical for the whole evolution process efficiency,
because it is performed in parallel inside each membrane in every evolution step. This work defines usefulness
states through an exhaustive analysis of the P system for every membrane and for every possible configuration of
the membrane structure during the computation. Moreover, this analysis can be done in a static way; therefore
membranes only have to check their usefulness states to obtain their set of useful rules during execution.

Abstract: Special generalizing for the artificial neural nets: so called RFT – FN – is under discussion in the report.
Such refinement touch upon the constituent elements for the conception of artificial neural network, namely, the
choice of main primary functional elements in the net, the way to connect them(topology) and the structure of the
net as a whole. As to the last, the structure of the functional net proposed is determined dynamically just in the
constructing the net by itself by the special recurrent procedure. The number of newly joining primary functional
elements, the topology of its connecting and tuning of the primary elements is the content of the each recurrent
step. The procedure is terminated under fulfilling “natural” criteria relating residuals for example. The functional
proposed can be used in solving the approximation problem for the functions, represented by its observations, for
classifying and clustering, pattern recognition, etc. Recurrent procedure provide for the versatile optimizing
possibilities: as on the each step of the procedure and wholly: by the choice of the newly joining elements,
topology, by the affine transformations if input and intermediate coordinate as well as by its nonlinear coordinate
wise transformations. All considerations are essentially based, constructively and evidently represented by the
means of the Generalized Inverse.

NEURAL CONTROL OF CHAOS AND APLICATIONS

Abstract: Signal processing is an important topic in technological research today. In the areas of nonlinear
dynamics search, the endeavor to control or order chaos is an issue that has received increasing attention over
the last few years. Increasing interest in neural networks composed of simple processing elements (neurons) has
led to widespread use of such networks to control dynamic systems learning. This paper presents
backpropagationbased neural network architecture that can be used as a controller to stabilize unsteady periodic
orbits. It also presents a neural networkbased method for transferring the dynamics among attractors, leading to
more efficient system control. The procedure can be applied to every point of the basin, no matter how far away
from the attractor they are. Finally, this paper shows how two mixed chaotic signals can be controlled using a
backpropagation neural network as a filter to separate and control both signals at the same time. The neural
network provides more effective control, overcoming the problems that arise with control feedback methods.
Control is more effective because it can be applied to the system at any point, even if it is moving away from the
target state, which prevents waiting times. Also control can be applied even if there is little information about the
system and remains stable longer even in the presence of random dynamic noise.
