figure out the pseudocode is to get some of the algorithms that are in
pseudocode in the book in Java, because I some experience with Java and
none with Lisp or Python. For some reason, I find the authors'
pseudocode style to be almost impossible to understand - even when I
find out how the algorithms work from other sources. I figure that if
I compare the pseudocode versions of the algorithm with version in a
language that I am more familiar with, I will finally be able to
understand the pseudocode style. If I look at examples in Lisp then I
am dealing with two languages I don't understand instead of one.
- I still think that you would find Norvig s book is written in a style that shows you algorithms stripped to their essence, yet they are fully executable code.Message 3 of 5 , Jan 1, 2008View SourceI still think that you would find Norvig's book is written in a style that shows youalgorithms stripped to their essence, yet they are fully executable code.You would soon learn how close Lisp is to the *ideas*.The way he defines and then builds on tree-search could hardly be anymore elegant. His page 191 shows the arguments are: states, goal-p,successors, and combiner. The latter three are functions passed asarguments. Successors is simply a list.It's nine lines of code plus two lines of comments,plus the variety of search strategies he presents in the rest of Sec. 6.4,all built on tree-search by using appropriate variants of the three functions.- Bob FutrelleOn Jan 1, 2008, at 9:27 AM, Michael B.

The English one is not so good but is ok:
Same for many other algorithms.
