关于图的最大匹配问题的若干结果

The study on the maximum matchings (as well as perfect matchings) of a graph plays a central role in matching theory. In addition to the algorithnis of finding maximum matchings, the structural properties of all maximum matchings are significant in theory or application aspect. Roughly speaking, the properties we are concerned in this thesis are mainly as follows:1. How many maximum matchings are there in a graph?2.   (本文共107页) 本文目录 | 阅读全文>>

Harmony search optimization applied to reservoir engineering assisted history matching

Based on the analysis of characteristics and advantages of HSO(harmony search optimization) algorithm, HSO was used in reservoir engineering assisted history matching of Kareem reservoir in Amal field in the Gulf of Suez, Egypt. HSO algorithm has the following advantages:(1) The good balance between exploration and exploitation techniques during searching for optimal solutions makes the HSO algorithm robust and effic...  (本文共7页) 阅读全文>>

Non-collinear phase-matching sum-frequency generation based on boundary total reflection in bulk KDP

Collinear phase-matching of sum-frequency generation(SFG) has been studied thoroughly previously, while non-collinear schemes are sometimes more flexible in application. However, this phase-matching type is more difficult to meet and control. We employ a convenient m...  (本文共6页) 阅读全文>>

Broadband quasi-phase matching in a MgO:PPLN thin film

Future quantum information networks operated on telecom channels require qubit transfer between different wavelengths while preserving quantum coherence and entanglement. Qubit transfer is a nonlinear optical process,but currently the types of atoms used for quantum information processing and storage are limited by the narrow bandwidth of upconversion available. Here we present the first experime...  (本文共5页) 阅读全文>>
