Meanwhile, during optimization, the proposed algorithm can gradually refine the decomposition to make it more accurate. Since little domain knowledge is required, the decomposition method has great adaptability to multiform networks. First, an iterative trace-based decomposition method is specially designed by utilizing the information of water tracing to divide a large-scale network into small sub-networks. In order to solve the large-scale water distribution network optimization problem, a cooperative co-evolutionary algorithm is proposed in this paper. Nowadays, the scale of the water distribution network of a city grows dramatically along with the city expansion, which brings heavy pressure to its optimal design. A good design of the network can not only reduce the construction expenditure but also provide reliable service. +++ linux-2.6.4.sched/kernel/sysctl.c 21:36:26.Potable water distribution networks are important infrastructures of modern cities. + max_timeslice = _MAX_TIMESLICE_DESKTOP ĭiff -uNrp linux-2.6.4/kernel/sysctl.c linux-2.6.4.sched/kernel/sysctl.c + min_timeslice = _MIN_TIMESLICE_DESKTOP +static int _init init_desktop(char *str) +int max_timeslice = _MAX_TIMESLICE, min_timeslice = _MIN_TIMESLICE +/* the sysctl values are exported in usec units to userspace */ + * Minimum timeslice is 10 msecs, default timeslice is 150 msecs, * Minimum timeslice is 10 msecs, default timeslice is 100 msecs, * These are the 'tuning knobs' of the scheduler: + KERN_HZ=69, /* unsigned long: interal kernel HZ */ĭiff -uNrp linux-2.6.4/kernel/sched.c linux-2.6.4.sched/kernel/sched.c + KERN_MINTIMESLICE=68, /* int: nice +19 min timeslice */
