What is the notation for inserting algorithms in scientific papers

I have some papers which describe some computer algorithms. My algorithms have some input, output, static (global) variables, comments ... something like the following algorithm, however I borrowed it from a book about artificial intelligence and I am not sure that is the style for a paper

function SIMPLE-REFLEX-AGENT(percept) returns an action 
    static: rules, a set of condition-action rules
    state← INTERPRET-INPUT(percept) 
    rule← RULE-MATCH(state, rules) 
    action← RULE-ACTION[rule] 
return action

What is the standard notation to insert such algorithms into a paper?
