Hello, you can take bus No.84 to dongxia or take a taxi to dongxia. Now the tourists have adjusted to the Dong wharf. If you want to go to Gulangyu, you are advised to buy tickets online in advance. There are only more than 300 seats on the cruise ship. If the seats are full, you have to wait for the off-ty ship

For most users, most of the classes provided in swarm can be used directly. In order to build a simulation environment, users need to construct some objects to represent real-life subjects. In most cases, these objects can be based on the classes that exist in swarm, which saves users a lot of transactional work. The following is a brief introction to several major class libraries available in swarm
the swarm object library includes two important classes, swarm object and swarm. Swarm object is the root class of all simulation agents. It defines the interface of memory management and provides support for probes. The swarm class is the master of the model, and both modelswarm and observersswarm inherit useful code from this base class
the activity library provides support for scheles. The schele is the time sequence list of the model running. The user can put the periodically executed actions into the data structure in order, and specify the running interval and trigger conditions. The model can run according to this Convention without human intervention
the simtools library includes classes that support probes so that variables can be observed or modified ring the running of the model. Simtools also provides data analysis and display support tools, which can generate statistical data summary, draw sequence diagram and so on
collections provides a list of objects, such as list, array, set, etc. Swarm supports passing messages to all objects in a list, and it can also sort the objects in the list by a certain attribute
support for message, error handling, debugging and memory allocation is provided in defobj, which enhances the function of Objective-C. It also supports the separation of object interface and implementation, which makes the hierarchy of the program written by swarm clearer
random library provides users with a set of random number generators. In computer simulation, the quality of random number generator is absolutely important. If the generated random number has deviation or correlation, it is easy to proce wrong results. Swarm's random number library supports normal distribution, uniform distribution, exponential distribution and other random distributions
space is a simple space library, including a series of classes for two-dimensional discrete models. These spatial types are often used in ecosystem simulation. Most of the classes in space are inherited from grid2d, a two-dimensional array that can store objects and integer values on a specified grid point
