If sufficient time is available, this method guarantees that the optimal result will be found. An estimate of the time to be taken can be obtained by clicking the Sample Run button.仿真,仿真论坛,仿真软件,物流仿真,供应链仿真,生产仿真,系统仿真,流程仿真,arena,anylogic,automod,extend,em-plant,flexsim,promodel,witness,乐龙,swarm,netlogo,repast; [) }# b) Q/ F5 B) Q+ R8 u
（2）Min/Mid/Max, which will run all combinations of min, mid and max settings of range parameters. For set parameters all values are used.

（3）Hill Climb, which is a simple method of searching for improvements. This method iteratively generates a single neighbor, which is accepted only if it is of higher quality. The neighborhood function selects a parameter at random; if the parameter is contiguous then it is either increased or decreased at random. Non-contiguous parameters are set to a value picked at random from their valid range.

（4）Random solutions, which generates random combinations and can help indicate how solutions will vary, by giving a picture of the shape of the entire solution space for a particular scenario./ v( a5 p$ D- p2 d& b
（5）Adaptive Thermostatistical SA (Simulated Annealing). Although basic Hill Climb can sometimes find a local optimal solution more quickly than other techniques, this is often highly dependent on the starting values chosen by the algorithm. In contrast, Adaptive Thermostatistical SA will not get stuck in local optima and is recommended for that reason.仿真,仿真论坛,仿真软件,物流仿真,供应链仿真,生产仿真,系统仿真,流程仿真,arena,anylogic,automod,extend,em-plant,flexsim,promodel,witness,乐龙,swarm,netlogo,repast$ l2 r- `5 `4 b# D u- s, g
