Task reallocation in a multi-robot organization is a process that distributes a decomposed global task to individual robots. This process must be distributed and dynamic because it relies on critical information that can only be obtained during mission execution. This paper presents a representation for this challenging problem and proposes an algorithm that allows member robots to trade tasks ...

Slow self-avoiding adaptive walks by an infinite radius search algorithm (Limax) are analyzed as themselves, and as the network they form. The study is conducted on several NK problems and two HIFF problems. We find that examination of such “slacker” walks and networks can indicate relative search difficulty within a family of problems, help identify potential local optima, and detect presence ...

We show that two popular discounted reward natural actor-critics, NAC-LSTD and eNAC, follow biased estimates of the natural policy gradient. We derive the first unbiased discounted reward natural actor-critics using batch and iterative approaches to gradient estimation and prove their convergence to globally optimal policies for discrete problems and locally optimal policies for continuous prob...

This paper introduces some known non-optimum to the networks security, categorizes the non-optimum, and analyses protection mechanisms and techniques for countering the non-optimum. The non-optimum have been classified more so as definitions and then followed by the classifications of these non-optimum. Also mentioned are the protection mechanisms. The paper establishes the syndrome and empiric...

| Optimum space-time convolutional codes, that provide maximum diversity and coding gain, are produced for cases with PSK modulation and various numbers of states and antennas. The codes are found using a new approach introduced recently in a companion paper. The new approach provides an eecient method that allows a search for optimum codes for many practical problems, while previous research w...

We give some new optimumGolomb rectangles found by computer search. AMS Subject Classi cation. 05B99 In [2] Robinson de ned a Golomb rectangle as an N M array of ones and zeros such that the two-dimensional autocorrelation has three values: 0; 1 and K, where K is the number of ones in the array. This means that the positions of the ones in any nonzero integral translation of the rectangle will ...

At least two control points must be available in order to determine the position and orientation of a total station (TS). This paper analyses optimum horizontal location of TS with respect to the control points and gives an answer to question “What is the best location of total station with respect to the control points if the goal is to determine the coordinates of TS and detail points as prec...

a central premise of monetary policy in the U.S. throughout the first decade of the 21st century has been a firm commitment to avoid deflation, that is, a persistent fall in the price level. indeed, it is the consensus view of policymakers and most economists.1 central premise of monetary policy in the U.S. throughout the first decade of the 21st century has been a firm commitment to avoid defl...

UNLABELLED Economic considerations suggest that it is desirable to keep operating rooms fully used when staffed, but the optimum utilization of an operating room (OR) is not known. We created a simulation of an OR to define optimum utilization. We set operational goals of having cases start within 15 min of the scheduled time and of having the cases end no more than 15 min past the scheduled en...
