", JDK 1.6 already have very good one. i am doing it for a company, but i also want to write something for a class about it. Could keeping score help in conflict resolution? The lesser the arrival time, the sooner will the process gets the CPU.
In this algorithm, the priority will be assigned to each of the processes. How do I efficiently iterate over each entry in a Java Map?

edit: actually glpk comes with it's own modeling language which is just a subset of AMPL, which would likely make things easier.
Scheduling algorithm is used by CPU scheduler to select a process .
So you have an existing framework modelling a computer and now you're expected to supply the CPU scheduling … There exists precedence relations between the activities, such that one activity j ∈ A can not be started before all its immediate predecessors have completed. I would suggest the GNU MathProg modeling language, it is a subset of the AMPL language and you can use it with the GLPK solver. So the instances I have to deal with are not solvable in practical time with this methods.
Each of the process will get the CPU for a small amount of time (called time quantum) and then get back to the ready queue to wait for its next turn. All rights reserved. When to use LinkedList over ArrayList in Java? The Quartz Scheduler includes many enterprise-class features, such as JTA transactions and clustering. Ask Question Asked 10 years ago. If you look at any operations research in this field you will see modeling as a MILP is by far the preferred approach.

AMPL is a modeling language that you can use for this, it can be compiled into a mixed integer linear program and solved with a number of solvers. Furthermore I will write my master thesis about that and so I will also have to tackle some PSPLIB instances for benchmarking.
