Aircraft Maintanence

I have a project where I want the same output but I want to change some Functions algorithm due to issue of plagiarism in the Dgraph1, Dgraph2 and Dgraph3 section and class-main function - In Dgraph3 - def find_all_paths(self, start, end, path = []): must be changed - def find_all_cycles(self, start): must be changed In Dgraph2 - def find_all_paths(self, start, end, path = []): must be changed - def find_all_cycles(self, start): must be changed In Dgraph - def find_all_paths(self, start, end, path = []): must be changed In the class main function - def Maintenance_Cost(self,flights, aircrafts): must be changed but shouldn't effect the output. def Reassignment_Cost (self,cycle, aircrafts): must be changed but shouldn't effect the output. I am attaching the (.IPYNB file) where you have to make the changes and the excel file that is used to read the data.
