Geometric Crossover for Permutations with Repetitions: Applications to Graph Partitioning
Geometric crossover is a representation-independent generalization of the traditional crossover defined using the distance of the solution space. By choosing a distance firmly rooted in the syntax of the solution representation as basis for geometric crossover, one can design new crossovers for any representation. In previous work we have applied geometric crossover to simple permutations. In t...
متن کاملArchitectural techniques for accelerating subword permutations with repetitions
We propose two new instructions, swperm and sieve, that can be used to efficiently complete an arbitrary bit-level permutation of an -bit word with or without repetitions. Permutations with repetitions are rearrangements of an ordered set in which elements may replace other elements in the set; such permutations are useful in cryptographic algorithms. On a four-way superscalar processor, we can...
متن کاملRepetitions and permutations of columns in the semijoin algebra
Codd defined the relational algebra [3, 4] as the algebra with operations projection, join, restriction, union and difference. His projection operator can drop, permute and repeat columns of a relation. This permuting and repeating of columns does not really add expressive power to the relational algebra. Indeed, using the join operation, one can rewrite any relational algebra expression into a...

متن کاملArchitectural Enhancements for Fast Subword Permutations with Repetitions in Cryptographic Applications
We propose two new instructions, swperm and sieve, that can be used to efficiently complete an arbitrary bit-level permutation of an n-bit word with or without repetitions. Permutations with repetitions are rearrangements of an ordered set in which elements may replace other elements in the set; such permutations are useful in cryptographic algorithms. On a 4-way superscalar processor, an arbit...
