Door tras is a chirurgical procedure in orthopedics in which there is generally a procedure in which part of the disk in the spine is removed. Tras is a form of an operation and is used for treating lumbar spine disease.

The idea behind it is that the nerves in the spine are also trapped in the spine. After removing part of the disk, the nerves are able to move freely and do not feel any pain.

Random walk on a matrix algebra – difference to standard random walk

I have been reading this (pdf) paper on random walks on algebraic graphs and the difference to the standard walk on the same graph.
With the standard walk, at every step, a random edge is chosen and the walker moves according to the probabilities given by the edge.
But with this walk, the probabilities are given by the square root of elements of the matrix $A$, e.g. the probability of the movement to the right is $\sum_k a_{ij}^k$ with the $a_{ij}$ representing the probability of staying at $i$ or moving to $j$ and $k$ representing the number of steps we have already taken.
In the paper in question, in page 35, it is claimed that this random walk is also called “coordinatewise random walk” and from page 34 onwards, they comment on the connection to random walks on matrix algebras.
Does anyone know how this walk is connected to standard random walks, i.e. how to start from $p_0=e_{ij}$ as in the standard walk, instead of $p_0=\sqrt{e_{ij}}$ as in the coordinatewise random walk?

In this case, Nalimov tablebases are not quite useful anymore. Using only Nalimov tablebases and the ideal endgame in chess with 12 pieces can be computationally hard and a possible reason why there is no endgame tablebases for 5-pieces is that they are not feasible computationally.

A:

I assume you are talking about Nalimov’s tablebases, (which were written by Lev Nalimov).
Nalimov’s tablebases give a good insight into why a chess game may end up in a certain drawish position. Many if not all of the drawish positions you encounter in a game of chess are covered by Nalimov’s tablebases.
Since you don’t seem to be interested in Nalimov’s tablebases, I’ll explain them briefly. If you want to know more about how Nalimov did it and how these tablebases were invented, you will have to read the paper by Nalimov himself or the more recent book by Baburin on the topic.
A Nalimov tablebase is an algebraic (or polynomial) relation between the pieces of the board. For each given position there is a number that tells how likely the game is to end in a draw, a number that tells how likely the game is to continue, and a number that says how many tables (cycles) you have to read to discover the final position of the game.

0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00

We have to read 0 tables to see that the game ends in a draw. Next, we have the 0.00 in the position where Black has 3 pawns (one on e5, one on d5 and the other on f5), and 3 pawns here are enough to win the game for White. So now we have,

0.25 0.50 0.50 0.00 0.00 0.00 0.00 0.00 0.00
