  • Relational Databases Query Optimization using Hybrid Evolutionary Algorithm 

    Safari Mamaghani, Ali؛ Asghari, Kayvan؛ Mahmoudi, Farborz؛ Meybodi, Mohammad Reza (Qazvin Islamic Azad University, 2008-02-01)
    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 ...

  • An Improved Standard Cell Placement Methodology using Hybrid Analytic and Heuristic Techniques 

    Jahanian, Ali؛ Saheb Zamani, Morteza؛ Khorram, Esmaeil (Qazvin Islamic Azad University, 2008-02-01)
    In recent years, size of VLSI circuits is dramatically grown and layout generation of current circuits has become a dominant task in design flow. Standard cell placement is an effective stage of physical design and quality ...

  • Semantic Preserving Data Reduction using Artificial Immune Systems 

    Ehsani, Seyed Amir؛ Eftekhari Moghadam, Amir Masood (Qazvin Islamic Azad University, 2008-02-01)
    Artificial Immune Systems (AIS) can be defined as soft computing systems inspired by immune system of vertebrates. Immune system is an adaptive pattern recognition system. AIS have been used in pattern recognition, machine ...
