11This program is a port of the GNU GO program by Man L. Li that utilizes the
12window GUI interface of the NeXT computer. To make moves on the board the
13human player only needs to click the mouse button while the cursor is
14pointed at the appropriate place on the board.
15
16The computer moves are all generated utilizing the basic methodology of
17GNU GO. However, there is one major addition to the GNU GO system. This
18addition is an automated scoring algorithm. These routines remove the
19obviously dead stones from the board and then count the score. A group is
20considered dead if it surrounds no territory and, if removed, the squares it
21covers would be owned by the opposing color. There is still room for
22improvement in this algorithm to remove those groups which only have one eye
23and are, therefore, also dead.
24
25This program also allows you to read and generate smart-go files. This is
26increasingly becoming the standard format for game storage on computer. It
27is a flexible format which allows for nested variations and can be a valuable
28format for storing educational examples.
29
30This program now also contains a client for the Internet Go Server. This
31client currently works through sockets and thus requires an actual internet
32connection. Future plans may include support for connecting via SLIP and/or
33modem. The client allows you to play on the IGS simply by clicking on the
34board and features a browser for the selection of games to observe.

8This program is the updated version of Hugo (Version 1.0). It is an
9attempt to start a free program to play Go. The idea is based on the
10article "Programming the Game of Go. Byte, Vol.6 No.4" by J. K. Millen.
11
12Currently, this program only understands basic Go rules and play skills.
13It counts the number of liberty for each board piece. Computer move is
14generated by choosing among several possible moves to attack the opponent,
15defense own pieces and match playing patterns. If no good move is found
16then random move will be generated. It doesn't have the concept of eye
17although it will try to form one.
18
19The program is written in C running on Sun and IBM PC. The only difference
20is the function to get system time as the seed for the random number
21generator. It can easily ported to other systems by changing this function.
22Computer Innovation C86 compiler is used for the PC version. To use other
23C compilers, simple change is required.
24
25You are encouraged to send in enhencement, suggestion, bug/fix for this
26program. Future release can be obtained from Free Software Foundation and
27usenet rec.games.go newsgroup.
