Sheet Cutting Algo Upgrade in C++

Hi Guys, I have C++ DLL (with source) used.. for paper cutting, sheet cutting plan.. giving a good results.. and working fine. now, we want to enhance the algorithm already written here, so that we get more better results.. For that - I have stock house of sheets (may be different sizes) and I have order of sheets (may be a list of different sizes) now software will take sheets from stock house and process them to fulfill the order optimally. wastage of stock (if usable size) will go back to the stock) every data is given as xml and the C++DLL results back in xml like (Stock_XML, Result_XML, Wastage_As_Stock_XML, Wastage_Only_XML) files so no need to give any database description.. xml contain simple <ID> <NAME> <SIZE> you can think your own.. no problem.. Condition to get this work: 1. you must demo me your sample application with sheet cutting functionality, I will demo mine (I dont want to waste my time and I dont want to give away my code to the one who is not skilled enough to write the algorithm himself - I hope you understand my concern)
