如何在杰森为另一个代理人发送规则？

Question

Jason带有一个使用表演性“tellRule”发送规则的演示，但在我的测试中它不起作用。我试图像这样发送给自我代理：

.send(self,tellRule, [{a :- b & c}])

结果是：

Command .send(self,tellRule, [{a :- b & c}]): included for execution
Communication error -- no_applicable: Found a goal for which there is no applicable plan:+!kqml_received(self,tellRule,[{ a :- (b & c)}],mid511)

Answer 1

实际上，Jason没有默认定义的“tellRule”表演。事实上，提到的demo正在教授如何添加KQML表演。那么，对于你的代码工作，你应该首先创建“tellRule”，这样做：

.send(self, tellHow, {+!kqml_received(A,tellRule,Rules,_) <- 
    .print("Received rule(s) ",Rules, " from ",A); 
    for ( .member(R, Rules) ) 
    {+R[source(A)];}  
    .relevant_rules(_,LR);       
    .print("Rules: ",LR)}).

在此之后，您可以运行命令：

.send(self,tellRule, [{a :- b & c}]).

顺便说一下，同样的想法可以用来创建类似“untellRule”的东西：

.send(self, tellHow, {+!kqml_received(A,untellRule,Rules,_) <-      
    .print("Removing rule(s) ",Rules, " from ",A);      
    for ( .member(R, Rules) )      
    {-R}}).
.send(self,untellRule,[{a :- b & c}]).
