Is it normal to take so long when the second move changes?
What is causing this problem?

If you are on a sidewalk and the covid goes beep beep
Just step aside or you might have a bit of heat
Covid covid runs through the town all day
Can the people ever change their ways
Sherwin the covid's after you
Sherwin if it catches you you're through

Re: What is causing this problem?
What is the exact meaning of the numbers in column 3 and 4 of each row?

Re: What is causing this problem?
By logic are nodes and nodes per second.
Not bad almost 6 M of nodes per second for Romichess with a single thread, this is 10 times more nps than my engine or perhaps I should buy new computer.

Re: What is causing this problem?
If the second move changes, that means move ordering was broken below that node. Not that unusual. Only thing I would do is compare the two PVs to make sure something is not broken to make you expend that kind of effort needlessly.

Re: What is causing this problem?
Indeed. The time to reach depth 21 was 4.2x the previous depth. Not something you'd want for every iteration, but definitely not something to be concerned about. Fail lows at the root can take 10x (or much more) to resolve. But, as Bob says, making sure that the search worked as intended is not unreasonable.bob wrote:If the second move changes, that means move ordering was broken below that node. Not that unusual.

Yes, nodes and nodes per second. Output is from Arena.pedrox wrote:By logic are nodes and nodes per second.

My computer is an i7 6 core overclocked to 3.8 gHz, water cooled.

Re: What is causing this problem?
Seems fine then. Match in progress. Romi vs Yace 0.99.87 +30 -30 =24. Romi usually performs sub par against Yace so equal is fantastic for Romi!bob wrote:If the second move changes, that means move ordering was broken below that node. Not that unusual.
