The best-first search algorithm A* allows search graphs that are trees, directed acyclic graphs or directed graphs with cycles. In real life applications of A* the search graph is generally implemented as a tree. It is shown here that for certain well known one-machine job sequencing problems...
technique based successively on the use of different priority rules and a local search procedure. An adequate criteria is developed to evaluate the quality of the assignment. The sequencing problem is solved by a hybrid genetic algorithm which takes into account the constraint of availability periods...
sequencing decisions is the main culprit in the difficulty of job shop scheduling. For regular objectives, the timing problem boils down to scheduling all operations as early as possible without violating the operation precedences within the jobs and the fixed operation processing sequences, and is ...
precedence relations. By performing the algorithm of Potts for the original and the inverse problem and taking the best solution, they established the existence of a-approximation. They also proposed two polynomial-time approximation schemes. A more effective PTAS has been proposed by Mastrolilli (20...

A significant contribution is made in the development of an effective and generic meta-heuristic approach for resource allocation, sequencing and scheduling, able to cope with various integrated decisions and a very large and complex search space. Our approach is needed by terminal operators because ...
Another job scheduling algorithm is shortest job first. In this approach (continuing the bank analogy), each customer is asked how many transactions he needs to make, and the one with the least number of transactions is served first. On average, this algorithm gives the best performance. Of ...
