To load this example and for sample queries, please see the SCRIPT file.
|
|
|
|
You will also need to load the following files in the library directory:
|
|
dates_loader, types_loader, events_loader, metapredicates_loader, and
|
|
hierarchies_loader. Alternatively, you can just load the library all_loader
|
|
file.

|
Some of the code in this folder is adopted from the book "Prolog Programming
|
|
for Artificial Intelligence" by Ivan Bratko.
|
|
|
|
For a description of the search problems, please see a classical AI book
|
|
(such as the one above) or visit the url <http://www.plastelina.net/games>.

|
This example defines two hierarchies of objects, one for representing
|
|
state-spaces and another for representing search methods:
|
|
|
|
state_space
|
|
farmer
|
|
water_jug
|
|
heuristic_state_space
|
|
bridge
|
|
eight_puzzle
|
|
miss_cann
|
|
|
|
search_strategy
|
|
blind_search(Bound)
|
|
breadth_first(Bound)
|
|
depth_first(Bound)
|
|
heuristic_search(Threshold)
|
|
best_first(Threshold)
|
|
hill_climbing(Threshold)
|
|
|
|
Taken together, these two hierarchies implement a framework for solving
|
|
state-space search problems in Logtalk.
