The job-shop scheduling problem is well known for its complexity as an NP-hard problem. We have considered JSSPs with an objective of minimizing makespan while satisfying a number of hard constraints. In this paper, we developed a memetic algorithm (MA) for solving JSSPs. Three priority rules were designed, namely partial reorder -ing, gap reduction and(More)
The Job-Shop Scheduling Problem (JSSP) is considered as one of the difficult combinatorial optimization problems and treated as a member of NP-complete problem class. In this paper, we consider JSSPs with an objective of minimizing makespan while satisfying a number of hard constraints. First, we develop a genetic algorithm (GA) based approach for solving(More)
The job-shop scheduling problem (JSSP) is a well-known difficult combinatorial optimization problem. Many algorithms have been proposed for solving JSSP in the last few decades, including algorithms based on evolutionary techniques. However, there is room for improvement in solving medium to large scale problems effectively. In this paper, we present a(More)
This paper presents a new heuristic algorithm for the Multiple-Choice Multi-Dimension Knapsack Problem (MMKP) in PRAM model. MMKP is a variant of the classical 0-1 knapsack problem, has a knapsack with multidimensional capacity constraints, groups of items, each item having a utility value and multidimensional resource constraints. The problem is to(More)

Digital image processing remains a challenging domain of programming. All digital images contain some degree of noise. Often times this noise is introduced by the camera when a picture is taken. Image denoising algorithms attempt to remove this noise from the image. In this paper the method for image denoising based on the nonlocal means (NL-means)(More)
— A band pass filter with tilted ladder shaped patch and U-shaped geometries is proposed in this paper. Feed are connected at the end of open ended stubs. Presented filter is suitable for the application of wireless application in L-band range. A flat passband response can be achieved when it is employed to implement a bandpass filter. The resonator also(More)
