Two-way Replacement Selection
The performance of external sorting using merge sort is highly dependent on the length of the runs generated. One of the most commonly used run generation strategies is Replacement Selection (RS) because, on average, it generates runs that are twice the size of the memory available. However, the length of the runs generated by RS is downsized for data with certain characteristics, like inputs s...

متن کاملA Model of Two-Way Selection System for Human Behavior
Two-way selection is a common phenomenon in nature and society. It appears in the processes like choosing a mate between men and women, making contracts between job hunters and recruiters, and trading between buyers and sellers. In this paper, we propose a model of two-way selection system, and present its analytical solution for the expectation of successful matching total and the regular patt...
متن کاملOptimal solutions in controlled selection problems with two-way stratification
When considering sample stratification by several variables, we often face the case where the expected number of sample units to be selected in each stratum is very small and the total number of units to be selected is smaller than the total number of strata. These stratified sample designs are specifically represented by the tabular arrays with real numbers, called controlled selection problem...
متن کاملRelay Selection and Resource Allocation in One-Way and Two-Way Cognitive Relay Networks
Relay Selection and Resource Allocation in One-Way and Two-Way Cognitive Relay Networks Ahmad Mustafa Alsharoa In this work, the problem of relay selection and resource power allocation in oneway and two-way cognitive relay networks using half duplex channels with di↵erent relaying protocols is investigated. Optimization problems for both single and multiple relay selection that maximize the su...
