Output message list

The in every case is the generation of a message, so the processing of the input messages leads to zero or more output messages being created. These are placed on an output message list. 

Each input message is compared with each classifier in turn. Once any triggered classifiers have created their output, the output message list is complete. 

Even for a small-scale problem, the classifier list may be long. This has the advantage that, since many classifiers may be able to generate output messages at one time, the system implicitly includes several different ways of responding to messages from the environment (in other words, it can incorporate several different hypotheses about how the environment behaves). This helps the CS to cope with uncertainty when there may be insufficient information on the input message list to determine precisely what state the environment is in. 

The order in which output messages are generated and placed on the output list is of no consequence, so the system can process information in parallel without worrying about whether one classifier should inspect the input list before another gets the chance. The number of messages posted to the output list is, in Example 1, equal to the number of classifiers, but in general the input and the output lists need not be equal in length either to each other or to the classifier list. 

The classifier system, which analyzes the input messages, creates messages for output, and places them on an output list. 

The first classifier is satisfied by the message oiooi and posts the message ooooi to the output list. If this is not a message to any effector, it will be transferred to the input list on the next major cycle and read by all the classifiers in that cycle. The message ooooi satisfies the second classifier, which would post the message oom in turn, this message activates the third classifier in the next cycle. 

A connector is implemented as the registration of the receiver s input with the sender s output. When a connection is to be made, the sender must be informed that the required output is to be sent to the required input of the required receiver. This explains what an output port is It represents an object s ability to accept registration requests and to maintain a list (a separate one for each of its output ports) of the interested parties. An input port represents an object s ability to accept the messages sent by the corresponding output ports. 

In LNT, gates are bidirectional. So we can present all AADL port directions in, out and in out. The correspondence between in/out ports is ensured with identifiers, every connection (from out to in port) has an identifier. Sender includes a list of connection identifiers in its output. has a list of accepted connection identifiers (parameter ConnectIDs) to verify if its is concerned by the received input. Thus, we can specify all AADL connection topologies. The Example presented in listings 1.3 and 1.4 transforms Producer/Consumer communication Producer provides inputs to two consumers Consumerl and Consumer2. This is an 1-to-n topology and event data type AADL port connection. In LNT, we get five processes. Process Producer sends messages. Each EventPort ConnPC identifies its concerned inputs with identifiers Producer D Consumer D. 

Rule 9. Bus becomes an LNT process , with two ports (input, output) modeling a queue with a capacity determined by a parameter. uses the push type where the communication is initiated by the sender. It allows the bound of any connection category data/event/event data connection and imme-diate/delayed connection. exchanges a message contained the following information sender identifier, list of connection identifiers, exchanged data and data sending interval time. 

Generate a list of 20 numbers between 1 and 100 using the Excel function RANDBETWEEN. Select these numbers and copy them (by value) to another column (the reason for this is that RANDBETWEEN updates the list each time an operation is performed in the spreadsheet). Write a VBA program to input the copied numbers and sort them into descending order using bubble sort. Output the sorted numbers to the spreadsheet. Be sure to give an error message if no numbers are entered.
