Identify a true statement about heuristics: a. They are more complicated than algorithms. b. Unlike algorithms, they do not permit rapid solutions. c. They require more scientific knowledge than algorithms. d. Unlike algorithms, they permit rapid decisions.

Can someone work out the answer as it comes up in one of my computer science exams and i don't understand the cryptovariables

Which computer network component connects two different networks together and allows them to communicate? a is a node (or a device) that connects two different networks together and allows them to communicate.

Acolor class has three public, integer-returning accessor methods: getred, getgreen, and getblue, and three protected, void-returning mutator methods: setred, setgreen, setblue, each of which accepts an integer parameter and assigns it to the corresponding color component. the class, alphachannelcolor-- a subclass of color-- has an integer instance variable, alpha, containing the alpha channel value, representing the degree of transparency of the color. alphachannelcolor also has a method named dissolve (void-returning, and no parameters), that causes the color to fade a bit. it does this by incrementing (by 1) all three color components (using the above accessor and mutator methods) as well as the alpha component value. write the dissolve method.
