HI...
I tried a lot to find the code in LISP that solve the TSP with the
A* algorithm ,so if anybody can help me i'll be very grateful to

Hi, All.

If someone can tell me how to calculate the log-likelifood value
listed on page 730, -2044, please help me!
I tried to calculate this by below code(in Java language),
but I got such an odd value, -4041...
What was wrong?? I'm totally confused...

Thanks a lot.

-- code below
double[] values = new double[7];
// for bag
values[0] = log(0.6) * (1000 * 0.6) + log(0.4) * (1000 * 0.4);
// for flavor (560 for total number of cherry)
values[1] = log(0.6) * (560 * 0.6) + log(0.4) * (440 * 0.6);
values[2] = log(0.4) * (560 * 0.4) + log(0.6) * (440 * 0.4);
// for wrapper (545 for total number of red wrapper)
values[3] = log(0.6) * (545 * 0.6) + log(0.4) * (455 * 0.6);
values[4] = log(0.4) * (545 * 0.4) + log(0.6) * (455 * 0.4);
// for hole (550 for total number of holed)
values[5] = log(0.6) * (550 * 0.6) + log(0.4) * (450 * 0.6);
values[6] = log(0.4) * (550 * 0.4) + log(0.6) * (450 * 0.4);

* log() means Math.log(value) / Math.log(2)

Hello all, this is brandon.  I was wondering if anybody had the
solution (in PYTHON) to this algorithm.  I will even take a template.
  thanks and have a happy thanksgiving

Check the book they already have given 3 heuristics for 8 puzzle.

1> Number of misplaced tiles pg 106/108
2> Manhattan distance pg 106/108
3> Gaschnig's Heuristic pg 135 prob 4.9

pages numbered according to Second Edition of the book.

hi,
Sec 4.2 of the book clearly explains two heuristic functions for the
eightpuzzle.
You might also want to look at the java implementation of both these
heuristics.
Regds,
  Ravi

How about the heuristics given in the text (p. 102 first edition)? One
of those is the sum of the Manhattan distances between blocks' current
positions and their positions in the solved puzzle.

Q2.3. What is difference between agent functions and agent programs?
and its part a.

a.  Can there be more than one agent program that implements a given
agent function? Give an example, or show why one is not possible.

I need help in this regard.

thank you
but I need a hueristic function better than
Number of misplaced tiles pg 106/108
Manhattan distance pg 106/108

Are you a computer program ?

Iván.

Hello Brandon,
may I have a look at your code ?

Iván.

no, i am a graduate student majoring in computer
science.  do you want these heuristics or not??  just
let me know

brandon

Hello,
to be precise, in the international second edition there are five
heuristics for the puzzle problem:
1) Manhattan,
2) misplaced tiles,
3) the maximum of the two above,
4) Gaschnig's heuristic (exercise 4.9)
5) the maximum of 1,2,4

I wonder if anyone here knows any other.
