DNA cryptography is a new promising direction in cryptography research that emerged with the progress in DNA computing field. DNA can be used not only to store and transmit information, but also to perform computations. The massive parallelism and extraordinary information density inherent in this molecule are exploited for cryptographic purposes, and several DNA based algorithms are proposed for...
This paper presents two ACO algorithms for information retrieval. Unlike existing works, the proposed algorithms address the problem for large scale data sets. The algorithms and a classical information retrieval method have been implemented for comparison purposes. Experimentations have been conducted on smart collections and random benchmarks. Numerical results show that for small collections of...
Information retrieval (IR) has been widely investigated these last decades and significant results have been applied to several domains like e-commerce, e-library and automatic medical diagnostics. However, very few studies in this area deal with artificial intelligence or AI tools. Knowing the power of meta-heuristics in problem solving, we suggest exploring information retrieval with an evolutionary...
The process of designing a parallel data warehouse has two main steps: (1) fragmentation and (2) allocation of generated fragments at various nodes. Usually, fragmentation and allocation tasks are used iteratively (we first split the warehouse horizontally and then allocate fragments over the nodes). The main drawback of such design approach (called iterative) is that it does not take into account...
