• Start program java -jar NMM.jar

Improvements Version 1 → 2

• Rev: 1 → Rev: 2 at three positions
• System.out.print("+") → System.out.print(" + ")
• comment "if scope remains ..., sth. is wrong" removed
• add 4 times if ((scope != 10000) && ... to prevent illegal comparison (token.value(best_from, best_to))
• add 2 times important {} after "prefer capturing central token" (all or none of the settings are changed)

• if (token.score_print(1 + move%2) == 0) ... followed by newline in case of if or else
• System.out.print("PLAYER[") ... System.out.print("] = "); now followed by System.out.println(PLAYER[move%2]);
• NMM (C) Dr. Klaus Rieger → NMM ©2010 Klaus Rieger
• System.out.print(" + ") → System.out.print("+!")
• System.out.print("move = "); System.out.println(move + 1);
• introduction of HOSTS, defining the number of used hosts
• introduction of move_timeout, host_timeout and host_waittime
  • in case of timeout:
    • move_timout++
    • recalculate without GRID
  • end of move:
    • host_timeout += move_timeout
    • printout waiting time and timeout (+new timeout)
  • hosts with timeout are skipped (if (0 < host_timeout[++grid_jobnumber%HOSTS]) ... if (1 < host_timeout[...] ...))
• long GRID_WAIT, long grid_waiting → GRID_WAIT >> 0...63 works fine
• introduction of duration[2] and time; printout total time of white and black after automatic calculation
• list of hosts expanded to 22

• System.out.print(" "); → System.out.print("\t");
• ... && (-9000 < best_scope)) // -9000 ... (-10000 → -9000)
• scope = 9000 removed, if (marking(b) < 0) [best_scope = -9000; ...] else [compare scope/best_scope only here!]
• calculate(int depth, int main) ... int best_scope = 10000; ... if (10000 == best_scope) System.out.print(" *** nothing found *** ");

• rm 0* → rm 0????? (only files of the right length will be removed)

Improvements Version 2 → 3

• various Rev:(:) 2 → Rev:(:) 3
• various (C) ... to (C) 2005-2011 Dr. Klaus Rieger
• ax-gx == gx-ax checked for x=1...6 (OK)
• ax-gx == gx-ax_one_sub checked for x=1...6 (→ remove switch (depth)...)

• NMM ©2010 Klaus Rieger → NMM ©2011 Klaus Rieger
• grid_waiting → grid_wait
• host_wait_time → host_wait
• use of constructor public Token(int attack)

• introduction of 9x00
  • detailed comment
  • int best_scope = 9000 + 100*depth
  • three times: -9000 → -9000 - 100*depth
  • remove disturbing output (nothing found)
• ATTACK
  • set by constructor: public Token(int attack)
  • read ATTACK: public int getAttack()

• new script
• copies NMM.jar and NMM prepare.sh to mintaka

• script rewritten
• function print_info_host()
  • copy NMM.jar from mintaka to other hosts
  • add hostname to host.txt
• hosts
  • correlate to AstroGridTest
  • non working hosts disabled
  • comments updated
