    It will be made clear in the question which one you are to use. If not it's up to you which one you use. I tend to prefer Kruskal's but where there are lots of nodes then it is easier and less likely to make a mistake to use a table and Prim's

    These are so helpful - my teacher set me questions without any solutions so I can't check my work, so it's great having the practice questions at the end to work on. :) Thank you for uploading this.

    HI Ainee. Thank you so much for your fantastic comment. It feels great to hear students find the videos useful - that's my aim. Myself and my colleague Mr Arnold make the vids in our freetime outside teaching. I teach in Wembley, London. Check out the website with loads more to help your studies at hegartymaths.c.o.m. and please share with your friends, family and school to spread the word. Have a great day. Mr H

    Put a hypen or dash e.g. -  this says there is no connection. Don't put zero as this would imply a weight of zero but a connection. Hope that helps. Mr Hegarty

    @robinesther5182 11 років тому

    just curious, how are we supposed to input the value into the matrix form if the nodes are not connected to each other(say there is no arc connecting A to B). so what value should we put in the matrix?I really hope you can reply soon.
