to get the power oracle bone frame, you can buy it from specific merchants, and the price is generally 3000 + bottle cap (more expensive than the house in Diamond City = =). These merchants are all weapon merchants, and there must be an empty power Oracle worktable near TA. When you buy the power oracle bone frame from merchants, you can buy it, Next to the power a workbench, there will be a power a bone frame without any parts and fusion core, and it will not be shown as "stealing"
at present, the dealers selling power oracle bone frames are as follows:
atomic cat repair factory Duke
Fanglin town kl-e-o (the Raider selling weapons and ammunition)
priderwin - Quartermaster officer
(each dealer has only one skeleton and will not replenish later)
if you think that the power oracle bone frames sold by the merchants are too few, That's the console
how to use the console:
1. First, stand on a flat ground, gaze at a point on the ground, and then open the console
2. Enter the character "player. Placeatme 0002079e" in the console
3. Click enter and exit the console. At this time, you will find that an empty power oracle bone frame will appear where you are looking
4. If the powered oracle bone frame is stuck e to uneven ground, open the console first, click the stuck powered oracle bone frame, and exit the console after seeing its code in the console, then align the center to another flat ground, open the console, and enter "move to player" to move the powered oracle bone frame to the new location you specify.
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
swarm is developed by using objective C language. In the early versions, writing swarm applications also enables objective C to provide support for Java language from swarm version 2.0, and may support JavaScript, C + +, python, Perl and other languages in the future. The latest version of swarm, swarm 2.1.1, can run in different versions of UNIX, Linux, Windows95, Windows98, WindowsNT and Windows2000
the simulation of social economic system is based on the theoretical research of complex adaptive system (CAS). Through "relatively simple micro indivial activities can highlight the complex behaviors at the macro level", it opens the way for social science research and practice to take the flight of modern new technology
1. What is swarm
since 1994, the Santa Fe Institute (SFI) has launched a research project to develop a tool set to help scientists analyze complex adaptive systems. This simulation tool set is called swarm. In 1995, SFI released a beta version of swarm
users can use the class library provided by swarm to build a simulation system, so that the agents and elements in the system can interact through discrete events. Since swarm does not have any constraints on the model and the interaction between model elements, swarm should be able to simulate any physical or social system. In fact, people are using swarm to write programs in a wide range of research fields, including biology, economics, physics, chemistry and ecology
the purpose of swarm project is to create an efficient, reliable and reusable software experimental instrument through the cooperation of scientists and software engineers. It can give scientists a standard set of software tools, just like providing a well-equipped software laboratory to help people focus on research rather than manufacturing tools
swarm is actually a group of class libraries written in Objective-C language, which is an object-oriented C language. Some graphical interfaces, such as charts, buttons and windows, are described by TCL / TK. At first, swarm can only run under UNIX operating system and X windows interface. In April 1998, with the release of version 1.1, swarm launched a version that can run on Windows 95 / 98 / NT. In 1999, swarm provided support for Java, which made swarm more and more beneficial to non computer professionals

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
3. Objects in the model
most swarm simulation programs include four types of objects. Modelswarm, observer swarm, simulation agent and environment. Modelswarm and observersswarm are subclasses of swarm class. Swarm class is the basic building block of swarm simulation. A swarm is a combination of a series of objects and their behavior scheles. The impersonator usually inherits methods from swarm object to provide support for probes and memory management. Different simulation systems have different environments. For example, the ecosystem is usually a two-dimensional flat environment, such as grid2d provided by swarm
1) modelswarm
generally, swarm applications include two swarm objects, modelswarm at the core and swarm object encapsulating the simulated model. Every object in modelswarm corresponds to every subject in the model world. After the user has defined all the objects and established the relationship for them, the last step of modeling is to put these agents into the modelswarm object
in addition to being a collection of objects, modelswarm also includes a schele of behaviors in the model. Users need to write a schele for these agents to reflect the time in the model by generating a series of behaviors with a specific order. The schele can be created by generating the instance object of the schecle class in the activity library, in which the ordered object / message pairs are filled. After the schele is set up, the swarm model can run
modelswarm also includes a series of inputs and outputs. Input is the model parameters: such as the number of objects, initial value, etc. The output is the value of the variables to be observed and the running results of the model
2) observer swarm
for computer simulation, only one model that can run is useless. We also need data collection tools to observe the model and record what happened. In swarm, observation is realized through the observersswarm object. Observer swarm is a special object, which can observe other indivials through the detector interface. For example, a detector can observe the average price of a commodity and establish a time sequence diagram to track its dynamic changes. Another detector can track the average income of residents and store the data in a file for future analysis
observer swarm is also a swarm, so it also includes a group of indivials and a behavior schele. The indivial of observer swarm is used to observe the detector and output interface, such as chart, two-dimensional grid point and so on. The behavior schele describes the sampling interval and sequence of each detector. By combining the modelswarm and observer swarm of a model, a complete experimental model is established. By using modelswarm and observer swarm, the interface of the model can be separated from the implementation of the model, and the model itself is still pure, just like a world under a glass cover. Different observer swarm can be used to implement different data collection and control protocols, but the model itself has not changed
3) simulation subject
the simulated subject in the model corresponds to the real economic participation one by one. For example, in the economic model, we need to define consumers, companies and even governments, banks, etc. Simulation agents usually exist as a group of objects in the simulation system. We should define methods and properties for them according to the actual situation. In a complex adaptive system, the simulation subject should have the ability of learning and evolution. This requires the definition of an independent cognitive component (which can be a sub object or a method) in the subject to process and respond to the stimuli from the environment. The process of learning or evolution can be simulated by neural network or genetic algorithm
4) environment
in the model, the simulation subject usually lives in one environment. Many simulation platforms limit this environment to a specific type, such as 2D grid. One of the features of swarm is that it doesn't have to design a specific type of environment. In swarm, the environment itself is also a subject, which is an object in object-oriented terms. For example, in an economic system, the market is an environment. Consumers and businesses inquire and quote through the market, and their transactions are matched in the market. The main body of the market may have some special methods and attributes different from other main bodies in the model, such as market participants or market state. But in swarm simulation system, its processing is no different from other agents
here, we briefly introce the logic structure of swarm simulation, hoping readers can have an overall understanding of swarm. For details of using various parts of swarm, please refer to the swarm library documentation and sample programs. Full documentation of these tools can be found on swarm's official home page
