Fridolin 2.0

[Engin]

I would say not more than 2300 CEGT Elos. But there are running tests in the CEGT tournament. So please be patient...

hello Christian,
hope i was not to fast to spot light your engine here that will be downloadable at your site.

Hi Engin,

not at all. I'am happy about your posting. Thank you! I hope to see you again somewhere!

Fridolin 1.0 and Fridolin 2.0 test games..v1.0 solid play but not spectacular
good results overall (see pgn file) Fridolin 2.0 solid but not spectacular..a bit deeper search than v1.0.....major flaw in Fritz gui..Lots of Time Losses
(almost every game)...takes its sweet time making the moves..needs some adjustment..Thx AR

What time control are you using?
No losses on time here so far?

Fridolin 2.0 Leiden that played in WCCC 2015 is for download here:

would be interesting to include this engine in tournaments besides Maverick engine

Awesome - just added a Mac exe to your package - you may download it here.

Also added the compiler options I used. Did not spend a lot of time - the standard icc defauts worked pretty well.

Benchmark: - Start Fridolin with no settings applied - type "go depth 17" (must type "uci" first)

Did someone get it to work under Linux? It compiles without problems, and I can get it to work in the terminal. Just a GUI don't recognize it:

PyChess: "There is something wrong with the executeable"
Scid hangs when loading Fridolin.

Under Linux, input & output are buffered.
I was able to make it work by modifying the function CConsole::init() in the file system.cpp. I just moved an #endif directive so that the setvbuf() calls are also executed under Linux. The corrected function code is:

Code: Select all

void CConsole::init(void)
{
    m_waiting = true;
    m_logging = false;

#if defined(IS_WINDOWS)

    DWORD dw;
    m_stdin = GetStdHandle(STD_INPUT_HANDLE);
    m_pipe = !GetConsoleMode(m_stdin, &dw);

    if (!m_pipe)
    {
        SetConsoleMode(m_stdin, dw &~ (ENABLE_MOUSE_INPUT | ENABLE_WINDOW_INPUT));
        FlushConsoleInputBuffer(m_stdin);
    }
    else
#endif
    {
        setvbuf(stdin, NULL, _IONBF, 0);
        setvbuf(stdout, NULL, _IONBF, 0);
    }

}

That works, thank you very much!!
