reasoning: Forward-chaining and backward-chaining ). Positive reasoning is also called the embedding method. It is driven by facts. It starts from an initial fact and constantly applies rules to draw conclusions. First, select a rule in the Candidate queue to enable the rule for reasoning, and record the conclusion as the evidence for the next reasoning. Repeat this process until no available rules can be selected or the required solutions are obtained. Reverse reasoning is also called indu

One of the most striking new features of Java SE 6 is script support embedded. By default, Java SE 6 only supports JavaScript, but this does not mean that Java SE 6 only supports JavaScript. Java SE 6 provides some interfaces to define a script specification, namely jsr223. By implementing these interfaces, Java SE

These classification directories allow your website to obtain high-quality external links, so as to improve the ranking.Currently, the most common Chinese website classification directories include open directories ODP and Yahoo! ODP, especially the Open Directory, is the basis for deep indexing by many search engines. You must first consider putting your website directory into it. Note the following when logging on to these classification directories:

number operations. Therefore, it is best to use the sharded counters technology recommended by Google to calculate the total number. Because blobstore is just out of the test phase, and other modules do not support static files (such as slice), for example, datastore only supports objects within 1 MB, at the same time, each application can only upload up to one thousand files, and the speed is not optimal. Therefore, we recommend that you use other
