Up: Neural Network Scheduler for Previous: Conditions of Constraint 
Alterated Points on ImplementationThe Java program actually differs in some points from the description above. When the number of the times is , comets can be observed at most. So the solution of the neural network should satisfy: the number of the cells which satisfy is nearly . Therefore the system counts the number of those cells when it calculates the , and if the number is larger than , it decrease the value of moreover. On the other hand, if the number of those cells is smaller than , it increase moreover. In this way the system tries to find the solution more quickly. Because a neural network method does not assures that it returns the best solution, the result may have some room to be improve. Therefore, the program optimizes the result after the network finished. It definitely makes the solution keep the condition that, when the solution says comet i should be observed at time j, the contition of the comet is worse at any other time, otherwise another comet should be scheduled to those time. If there is a time k when the condition of the comet is better than at than at time j and no other comet is scheduled at that time, the program modifies the comet should be obsreved at time k. It does the check for all comets.
