How is movement determined?

how come in SP games, the AI keeps attacking my armies with tiny forces, halting its movement into their provinces? Happens all. the. time. in SP games.

The AI is quite good in SP games at raiding and running away from your main force. You have to keep an equally well defended border of provinces to him and slowly bulldoze forward towards him, or lay a trap and hope that he falls for it (remember, friendly movement happens before hostile movement, so you can send all your armies as defenders to a previously undefended province of yours and maybe intercept him)
