Problem: i need to use function boolean run through an algorithm to check the dominance of array $ds, and sort the point base on it dominancy. Note: the algorithm below is given by my profesor.
Example= given a set of array like below $ds, i wish to sort the points based on it dominancy after running through the alogorithm in boolean function below.
Note: Points = one of the array rows = array(1,11,5) //juz an example to tell wat i mean by points.
i have been thinking for so long on how to perform this task. My profesor said it is juz a simple task.
<?php
function A(){
$ds = array(
array(1,11,5),
array(2,6,7),
array(3,13,9),
array(12,7,16),
array(14,3,25),
array(19,18,22),
array(23,13,29),
array(24,4,28)
);
return $ds;
}
function boolean(){
$ds=A();
$p=$ds[1];
$d = 3;
$n =8;
for($i = 0; $i < $n; $i++){
if ($ds[$i]!= $p){
$it=0;
$eq=0;
for($j = 0; $j < $d; $j++){
if($ds[$i][$j]<$p[$j]){
$it++;
}
elseif($ds[$i][$j]==$p[$j]){
$eq++;
}
}
if(($it+$eq==$d)&&($it>0)){
return false;
}
}
}
return true;
}
if ( boolean == true) {
echo "<pre>";
print_r ($p[$j]);
}
else {
echo 'Something has defiantly gone wrong...';
}
?>
