bs -- battleships game
This program allows you to play the familiar Battleships game against the
computer on a 10x10 board. The interface is visual and largely self-
explanatory; you place your ships and pick your shots by moving the cur-
sor around the `sea' with the rogue(6) / hack(6) motion keys
Note that when selecting a ship to place, you must type the capital let-
ter (these are, after all, capital ships). During ship placement, the
`r' command may be used to ignore the current position and randomly place
your currently selected ship. The `R' command will place all remaining
ships randomly. The ^L command (form feed, ASCII 12) will force a screen
The command-line arguments control game modes.
-b selects a ``blitz'' variant
-s selects a ``salvo'' variant
-c permits ships to be placed adjacently
The ``blitz'' variant allows a side to shoot for as long as it continues
to score hits.
The ``salvo'' game allows a player one shot per turn for each of his/her
ships still afloat. This puts a premium scoring hits early and knocking
out some ships and also makes much harder the situation where you face a
superior force with only your PT-boat.
Normally, ships must be separated by at least one square of open water.
The -c option disables this check and allows them to close-pack.
The algorithm the computer uses once it has found a ship to sink is prov-
ably optimal. The dispersion criterion for the random-fire algorithm may
