Hi Mahmood,

The ROI begins just from "transaction number is 500000". 

Best Regards,
Yungang

Hi, 
I want to know when the main code of freqmine is executed considering this output: 


transaction number is 500000 
1522 
13083 
44649 
118072 
337195 
904434 
1946385 
3281416 
4382543 
4694188 
4068013 
2864888 
1636526 
750500 
270740 
74394 
14841 
1992 
156 
5 
the data preparation cost 337.142548 seconds, the FPgrowth cost 2453.190156 seconds 



In another word, does the ROI begin after " transaction number is 500000" or it begins after the numbers? 
Regards,
