# How to remember the Decisions 1 algorithms for A level maths? Watch

1. Hey so guys im struggling with my D1, actually self teaching

Whats the best way to differentiate all the algorithms? im struggling to remember the methods of each question, however when i get started i know what i'm doing, just need a trigger to tell me what method to do! For Primms, Kruskals, Chinese postman, Nearest Neighbour, Lower Bound and Dijkstras

I can only think of one for chinese postman and its to remember that the postman has to visit all the streets so i know its all the edges, add the shortest route onto the end

The most important thing is that you practice and know how to each one - maybe, as you do it, write the name of the algorithm you're using. I'd tell you what mnemonics I used but I can't remember them
