Publius - public domain teaching engine

[Joost Buijs]

Looks nice. When building in VS 2022 it doesn't recognize the clamp function in eval. What to do?

Edit i changed it to this:

// Make sure eval doesn't exceed mate score
//score = clamp(score, -EvalLimit, EvalLimit);
if (score < -EvalLimit) score = -EvalLimit;
if (score > EvalLimit) score = EvalLimit;

I hope that behaves the same...

std::clamp() is a C++20 function, when you set MSVC in the project properties to C++20 it will recognize std::clamp().
Make sure to include <algorithm>, that's where it is defined.

Thans Joost, old Warrior So it's in a package (or option) that isn't installed (yet). I will dive into that.
Can you tell if my replacing code does the same?

Bart, long time no see. Yes, your code does the same. You don't have to install anything, it's just a setting in the compiler options:
Configuration Properties/General/C++ Language Standard

Thanks again Joost. That did the trick.

The low nps and output stall was because of compiling to debug mode...

There is a tabulation at end of line 12 of makefile that prevents it to work by me.

FYI, I downloaded the projet today and the makefile was broken again for the same reason.

By the way, you could simply do this:

Code: Select all

SRCS = $(wildcard *.cpp)

But I guess that you already know.

I use this makefile now:

Code: Select all

SRCS=$(wildcard *.cpp)

publius: $(SRCS)
	g++ -o publius $(SRCS) -O3 -flto

clean:
	- rm *.o publius

The options -O3 and -flto are necessary. Without these options Publius plays a lot weaker than 2800.

@Werner

Good to know. Thank you!

P.-S. With -flto option I get this warning. No idea of what it means.

Code: Select all
