No. You have to see your map if you don't require a minimal surplus.

The current version creates all possible actions based on some
constrains. These are currently:

+struct sma_actions_constrains {
+  int maximal_turns_to_reach_position;
+  struct {
+    /*
+     * Distance of the target position from the nearest city.
+     */
+    int minimal_distance, maximal_distance;
+
+    /*
+     * Minimal defense bonus of the target position.
+     */
+    int minimal_defense_bonus;
+  } city_building_constrains;
+};

There is no problem to extend this struct to also omit certain
actions. 

The current version also allows the injection of external actions. The
action generation will never produce action which would yield nothing
(a fortess for example) since it can't weight how much (food, trade,
shield) a fortess is worth. However there may other parts (other
agents like a defense agent of a city) of the code which know how much
terrain improvement can be sacrifice to build this fortess. So these
agents can inject a fortress action. This action would have some
artifical yields attached. These are considered if a settler have to
choose which action to carry out next.

The current version doesn't do this but these are only small
extensions.

Thanks.
