Ii. Under WAMIt has been imperative for decades. Functional or logical language compilers are broken down in several steps. In particular, an abstract machine is used as a high-levelSource codeAnd low-level executable targetsCodeThe intermediate layer between them. In fact, since Pascal and p-code, the abstract machine has been emphasizing as the backbone of the compilation process. The logic language is no exception here. compiling a Prolog Into a wa
Using off-the-shelf pagesA little trick.In the VIP development environment, you can test your code at any time without having to compile it into an EXE file.For example, to see the execution results of the VIP built-in predicate filenameext, you can write in a blank.

We describe the current situation and provide the preliminary performance test results for the prolog to C compiler. The compiler is novel when
An error occurs during webwork verification. The message "content is not allowed in Prolog" is displayed. If an error occurs while parsing the XML file, find the corresponding file, I found that I forgot to comment out several lines of Chinese characters at the beginning. I commented out them and the problem was solved. Because I had not encountered such a problem before, I found the following information on the Internet:Dom4j may encounter an error w
Study Notes on building an Expert System Using Prolog (4)
Iv. Description It is said that one of the important functions of the expert system is self-explanation of its behavior. This means that users can ask questions to the expert system at any time during the consultation process, why is it giving a certain answer, and the system will give an explanation according to certain rules.
1. Meaning of the interpretation function for users The user does

So far, we have a basic understanding of Prolog, and it is necessary to make a systematic summary of what we have learned.
The Prolog program is a database of facts and rules.
The call between the rules is done through a federated operation, and the Prolog can automatical

The core of Geni--Inference Machine (2) Process Control1, in detail fail, "!" and backtrackingCompared with other languages, the most important feature of Prolog is its backtracking mechanism.Backtracking mechanism, the main means are 2, one is to use the predicate fail to trigger the backtracking, and the second is to use the special verb "!" (read as cut) cancels backtracking.Prolog uses fail to trigger backtracking, to realize the cycle of the prog

5. The gnu prolog program creates a GUI in a novel and reasonable manner.
It is lightweight and small, and does not have a dedicated GUI function mechanism, but it can call GTK-server to enable its program to implement the GUI.
GTK-server needs to be downloaded and installed separately. Address: http://www.gtk-server.org/
