【问题描述】:
只是一个非常简单的问题。
我已收到此文件,我想运行它。
我相信它需要命令行参数才能与function trees_main(puzzle_ind,print_f,nls) 一起工作,但我不确定。它是几个不同文件的一部分 - 但这是主控制器。
关于如何向函数传递一些参数的任何想法?是在运行时完成的吗?
% A* search tree algorithm for solving 8 puzzle problem
% Inputs:
% puzzle_ind = 1:30
% print_f = 0/1, 1 to show the step solutions
% nls = 0/1, 1 to Nilsson Score
% Calls:
% trees (A* search)
% trees_gm (Generate moves)
% trees_mh (Manhattan metrics)
% trees_nls (Nilsson sequence)
% Uses:
% combinations.mat (30 resolvable puzzle combinations)
%
function trees_main(puzzle_ind,print_f,nls)
global Tg T0 T1 nls_f % These variables are visible in all functions
nls_f = nls;
Tg = [1 2 3; 8 0 4; 7 6 5]; % Goal sequence
% Coordinates (row and column) of tiles in a puzzle
T0 = [1 1; 1 2; 1 3; 2 1; 2 2; 2 3; 3 1; 3 2; 3 3];
T1 = [1 2 3 8 0 4 7 6 5];
load combinations Cmb
if puzzle_ind >= 1 && puzzle_ind <= 30
P = Cmb{puzzle_ind}; % assign the Puzzle
[T,n1,n2] = trees(P,print_f); % call A* search function
fprintf('\nPuzzle:\n')
fprintf('% 1i %1i %1i\n',Cmb{puzzle_ind}')
fprintf('Solution:\n')
fprintf('% 1i %1i %1i\n',T')
fprintf('Number of nodes = %4i\nNumber of moves = %2i\n\n',n1,n2)
end
trees_plot(puzzle_ind); % statistics
return
function trees_plot(pind)
global N1 nls_f
M = (N1(:,[2 8])');
n = size(M,2);
plot(1:n,M)
xlabel('Number of Tested Nodes')
ylabel('Metrics (without cost)')
if nls_f == 0
s1 = 'No';
else
s1 = 'Yes';
end
title(sprintf('Puzzle Index %2i, NSS %s',pind,s1))
axis([1 n 0 max(M(1,:))+1])
grid on
text(5,15,'Level (Cost)')
return

你在网上搜索过这个吗? MATLAB 有很好的文档,这是一个非常基本的问题。
