Goal oriented ranking scheme

A. R. Khaparde, A. Mokhade, P. D. Dahiwale
2010 Proceedings of the International Conference and Workshop on Emerging Trends in Technology - ICWET '10  
But one of criticism of EAs is lack of efficient and robust generic method to handle the constraints.  ...  One way to handle the constraint is use the penalty method .in this paper we have proposed a method to find the objective when the decision maker (DM) has to achieve the certain goal.  ...  The computational complexity of ranking scheme is .Note that if no feasible solution is present in the population (N=0), the ranking according to the constraint and objective ( ), and when P=N the ranking  ...

On the rank of p-schemes

Fatemeh Barandagh, Amir Rahnamai Barghi
unpublished
A sharp upper and lower bounds on the rank of schemes in C p n with a certain order of thin radical are obtained.  ...  Finally, it is shown that the scheme with minimum rank in C p n is unique up to isomorphism, and it is a fusion of any association p-schemes with degree p n .  ...  Acknowledgements The authors would like to thank Professor Ilia Ponomarenko for his valuable arguments in Example 6.  ...

THE p-TORSION OF CURVES WITH LARGE p-RANK

RACHEL PRIES
2009 International Journal of Number Theory  
It is an open problem to classify which group schemes occur as the p-torsion of the Jacobians of these curves for f < g − 1.  ...  Consider the locus of smooth curves of genus g and p-rank f defined over an algebraically closed field k of characteristic p.  ...  Recall that f X = dim F p Hom(µ p , J X [p]) where the group scheme µ p is the kernel of Frobenius on G m . Using [17] , one can compute the p-rank of X for a fixed choice of curve X and prime p.  ...

Recursive constructions for perfect secret sharing schemes

Hung-Min Sun, Shiuh-Pyng Shieh
1999 Computers and Mathematics with Applications  
In this paper, we propose some recursive constructions for perfect secret sharing schemes with access structures of constant rank.  ...  The information rate of a secret sharing scheme is defined to be the ratio between the size of secret and the maximum size of the shares.  ...  We define p(re, n) to be the lower bound of the information rate of secret sharing schemes with uniform access structures of rank re on n participants.  ...

A short guide to p-torsion of abelian varieties in characteristic p [article]

Rachel Pries
2006 arXiv   pre-print
There are many equivalent ways to describe the p-torsion of a principally polarized abelian variety in characteristic p.  ...  We briefly explain these methods and then illustrate them for abelian varieties A of arbitrary dimension g in several important cases, including when A has p-rank f and a-number 1 and when A has p-rank  ...  We denote this group scheme by L. Example 2.2. Let α p be the kernel of Frobenius on G a . As a k-scheme, α p ≃ Spec(k[x]/x p ).  ...

Fissions of Classical Self-Dual Association Schemes

D. de Caen, E.R. van Dam
1999 Journal of combinatorial theory. Series A

An alternative direct proof of Gibbard?s random dictatorship theorem

Yasuhito Tanaka
2003 Review of Economic Design  
Gibbard(1977) showed that when the number of alternatives is finite and larger than two, and individual preferences are linear (strict), a strategy-proof decision scheme (a probabilistic analogue of a  ...  social choice function or a voting rule) is a convex combination of decision schemes which are, in his terms, either unilateral or duple.  ...  The value of the probability of an alternative does not depend on what alternative it is, but depends on for whom it is the top-ranked alternative.  ...
