  • Hello, I have implemented wumpus problem by prolog by goal-based agent. I have my original of rules of shooting are not good. My first version: 1. rule: if and only if the agent can be sure that the "wumpus" is in front of him, He will shoot. 2. result: The shooting condition is too restrict, that in most time, it is impossible for agent to collect so much facts to make inference...

  • I think you are right. Because the environment also our program, rather than a real-world's thing. kind regards chenyu --- In aima-talk@^$1, Mauricio Amaral de Almeida wrote: > Someon please correct me if I wrong, but in my interpretation the actuators as > in conceptualy part of the agent. > But when you make a software implementation on the pair agent- environment you > have to...

  • Hello, I have asked others to help me to translate it from Japanese language. But it make me dispointed because it doesn't contain any information about how to learning. This documents mainly discuss the software "Mr.Log"'s brief information. This software use "TS (tubu search)" and "SA(simulated annealing)" to solve the problem. But after comparing many algorithm (methodology), I...

  • Hello everyone, I am trying to implement "wumpus problem" by prolog according to chapter 7 of AIMA version 1 first order logic description. Mr.Author called the system containing this goal-based agent as action-valued system because its action has been classified as "great desired, good desired, medium desired, risky desired". My implementation of 1 rules is follows: 1. if percept...

  • Hello, I have read part of Mr. Norvig's PAIP code and run some examples. Here some advice is given, and I hope it is helpful to you. 1. I have found PAIP code are written before 1997, it means that they are old code and haven't be maintained by 7 years. Maybe bugs haven't found by the writer after previous modification. Maybe your compiler is not 100 percent compatible to the...

  • Hi, I have found a introduction which is about VRP as a learning problem. But it is written in Japanease, I can't understand it now. After asking helping others for translation, I could reply you later. The website: http://citeseer.ist.psu.edu/ contains many paper about VRP. Maybe keyword of "learning VRP" will help you found many similars. In addition, I found some useful...

  • Hello everyone, I have downloaded AIMA version 2 sample chapter 5 and am doing its exercises. In exercise 5.7, it requires to compare the algorithms of MRV, forward checking, FC+MRV, Min-conflicts. But I wonder is it possible to implement MRV independently without FC? My impossible reasons are as follows: 1. MRV means "minimium remaining values". It means the unassigned variable...

  • Hello Hugo, I have use "notepad" to format the reply and eliminate the special characters. I hope it is readable now. In addition, for your program's problem (don't work), maybe firstly test the simplest planning problem as follows (context) to find the error, then comparing with the pceudo-code to find the problem. I haven't start this implementation now. kind regards/chenyu...
