Molecular biological databases: evolutionary history, data modeling, implementation and ethical background

Evolutionary Computation: The Background A2.3 A history of evolutionary computation

This section presents a brief but comprehensive summary of the history of evolutionary computation, starting with the ground-breaking work of the 1950s, tracing the rise and development of the three primary forms of evolutionary algorithms (evolution strategies, evolutionary programming and genetic algorithms), and concluding with the present time, in which a more unified view of the field is e...

modeling loss data by phase-type distribution

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...

Relational Databases Query Optimization using Hybrid Evolutionary Algorithm

Optimizing the database queries is one of hard research problems. Exhaustive search techniques like dynamic programming is suitable for queries with a few relations, but by increasing the number of relations in query, much use of memory and processing is needed, and the use of these methods is not suitable, so we have to use random and evolutionary methods. The use of evolutionary methods, beca...

Light-weight integration of molecular biological databases

MOTIVATION Due to the increasing number of molecular biological databases and the exponential growth of their contents, database integration is an important topic of research in bioinformatics. Existing approaches in this area have in common that considerable efforts are needed to provide integrated access to heterogeneous data sources. RESULTS This article describes the LIMBO architecture as...
