Hybrid algorithm is proposed to solve combinatorial optimization problem by using Ant Colony and Genetic programming algorithms. Evolutionary process of Ant Colony Optimization algorithm adapts genetic operations to enhance ant movement towards solution state. The algorithm converges to the optimal final solution, by accumulating the most effective sub-solutions.

I Which size? Trade-off I Minimum size: connectivity by recombination is achieved if at least one instance of every allele is guaranteed to be be present at each locus. Ex: if binary: P∗ 2 = (1− (0.5) ) for l = 50, it is sufficient M = 17 to guarantee P∗ 2 > 99.9%. I Often: independent, uninformed random picking from given search space. I Attempt to cover at best the search space, eg, Latin hyp...

Intruders often combine exploits against multiple vulnerabilities in order to break into the system. Each attack scenario is a sequence of exploits launched by an intruder that leads to an undesirable state such as access to a database, service disruption, etc. The collection of possible attack scenarios in a computer network can be represented by a directed graph, called network attack gra...

The edges of an image define the image boundary. When the image is noisy, it does not become easy to identify the edges. Therefore, a method requests to be developed that can identify edges clearly in a noisy image. Many methods have been proposed earlier using filters, transforms and wavelets with Ant colony optimization (ACO) that detect edges. We here used ACO for edge detection of noisy ima...

To enhance the optimization ability of ant colony optimization, this paper proposes a Bloch sphere-based quantum-inspired ant colony optimization algorithm. In the proposed approach, the positions of ants are encoded by qubits described on Bloch sphere. First, the destinations of ants are obtained by the select probability designed by the pheromone and heuristic information, and then, the movem...

In 1993 some hybrid technics combining OFDM and code division multiple access (CDMA) were proposed [3]. One of that technics is multicarrier code division multiple access (MCCDMA) witch introduce frequency spreading and multiple access. Both, OFDM and MCCDMA, have disadvantage in high peak to average power ratio (PAPR). There are many PAPR reduction schemes are for OFDM and most of them is usef...

This paper aims to find an effective and efficient information hiding method used for protecting secret information by embedding it in a cover media such as images. Finding the optimal set of the image pixel bits to be substituted by the secret message bits, such that the cover image is of high quality, is a complex process and there is an exponential number of feasible solutions. Two new ant-b...

This paper presents a new algorithm for clustering which is called an “efficient ant colony optimization clustering algorithm” (EACOC) based on a classic algorithm “LF algorithm”. We have proved the algorithm efficiency when dealt with a big variety of different data as well as providing high quality and converging speed simultaneously. This is considered as the outcome of many changes we have ...

Since its introduction, ant colony optimization (ACO) algorithms and especially the MAX-MIN ant system (MMAS) [4] are found to be well suited for many challenging optimization problems. Our theoretical analyses of MMAS allowed us to create the new algorithm, named the three bound ant system (TBAS), which has lower computational complexity and at the same time retains and even improves the quali...
