{
PL=QL[i-1];
Distance=GetDistance(PL,P);
Time=GetTime(PL,P);
V=Distance/Time;
If(V<=4000/7)
{
PL.remark=" points of trust ";
P=PL;
}
else
{
PL.remark=" suspicious points "; }
}
for(intj=0;j<=QR.Length-1;j++)
{
if(PR.Type==”GPS”)
{
P=PR;
Continue;
}
else
{
PR=QR[j];
Distance=GetDistance(PR,P);
Time=GetTime(PR,P);
V=Distance/Time;
If(V<=4000/7)
{
PR.remark=" points of trust ";
P=PR;
}
