So now for big changes! I recently started a new job at drive.ai working as a simulation engineer. For those that don't know, my research background is in simulation and training in virtual environments. I'm happy to be applying some of this knowledge to self-driving cars and happy that drive.ai is supportive of me continuing to run Algorithms Live!
The other piece of exciting news is I moved to California. I've finally met Lewin in person and hopefully will meet many other competitive programmers in the bay area and have them on the show. :)
Being in California allowed me to finally attend one of Donald Knuth's Christmas lectures in person. Many of you will remember my Christmas tree lecture from last year. This year was a bit different. Donald gave an exploratory lecture where he demonstrated the excitement of diving deep down rabbit holes while doing research and some combinatorial geometry. It was exciting and humorous but oddly enough, the lecture was not about trees!
I'm going to rectify this dilemma, as it wouldn't be Christmas without talking about one of my favorite classes of graphs. This week's episode will once again feature Lewin Gan. We will discuss his ACM ICPC problem "Rainbow Roads" that was used in several regions in the US. You can try the problem by solving one of the following regionals in Codeforces gym:

This will be my last episode of 2017 to ease back into things. I'll be going on holiday break this week, but will start running regular weekly episodes at the start of 2018. I've missed running this show and hope that many of you will like the future episodes to come!
Hello Matt you are doing a nice job.
ReplyDeleteThank you very much.
I am weak in Dynamic programming please take a live class on DP problems and concepts. How to think or approach to DP problems is very difficult for me.

I was diagnosed of herpes 3 years, and ever since then i have been taking treatment to prevent outbreaks, burning and blisters, but there was no improvement until i came across testimonies of Dr. VOODOO on how he has been curing different people from different diseases all over the world, then i contacted him. After our conversation he sent me the medicine which i took according to his instructions for up to 2 weeks. After completing the medication i went back to my doctor for another test and the virus was all gone and i was completely cured, since then i have not had any signs of outbreak.

DeleteI really want to thank Dr Emu for saving my marriage. My wife really treated me badly and left home for almost 3 month this got me sick and confused. Then I told my friend about how my wife has changed towards me. Then she told me to contact Dr Emu that he will help me bring back my wife and change her back to a good woman. I never believed in all this but I gave it a try. Dr Emu casted a spell of return of love on her, and my wife came back home for forgiveness and today we are happy again.

I got my ex husband back to me and also got fertile and gave birth to twin girls after 12 years of marriage.
When I came online last year, I saw a testimony about Doctor ODUNGA and how he has been helping people with marriage issues and I decided to contact him. We spoke on email at odungaspelltemple@gmail.com and later he gave me his WhatsApp number which is +2348167159012. He assured me he would help me get my ex husband back after 3 years of no contact. Doctor Odunga is the best spell caster I must say. My husband called me after 24 hours of contact. The third day, I received natural herbs for fertility and after using it, I became fertile and conceived. I and my husband reconnected, had sex and I was pregnant. Presently I am happy to say I am the mother of twin girls and this is ALL THANKS TO DOCTOR ODUNGA. I came online to say this If you need help, I believe you are saved with this man.

Happiness is all I see now I never thought that I will be cured from herpes virus again. I have been suffering from a deadly virus (HSV) for the past 4 years now, I had spent a lot of money going from one place to another, hospitals have been my home every day residence. Constant checks up have been my hobby not until this faithful day I was searching through the internet, I saw a testimony on how DR KOJO helped someone in curing his Herpes virus, quickly I copied his contact and I spoke to him, he told me that there is no medical hospital that has the cure for herpes virus, I was surprise when I heard that from him, he asked me to do some certain things which I did, he told me that he is going to provide the herbal remedy to me which he did then he asked me to go for a medical checkup after some days after using the herbal remedy behold I was free from this herpes virus, he only asked me to post the testimony through the whole world, faithfully am doing it now please BROTHER, SISTER, MOTHER and FATHER, he is a great man, I own him in return. if you are having a similar problem just Contact him on>kojosolutionhome@yahoo.com
