// these macros get expanded on the host if the @1 army is AI controlled

// Summary of node control AI approach is this:
//
// At startup, randomly pick one of these actions:
// 1. send sarge and group 1 to nearest non-owned node to sarge, send group 2, 4 and 6 to
//    second nearest non-owned node to sarge and send group 3, 5 and 7 to third nearest
//    non-owned node.
// 2. send sarge and group 1, 4, 5 to nearest non-owned node to sarge and send groups
//    2, 3, 6, 7 to second closest non-owned node to sarge
// 3. send sarge and all groups to nearest non-owned node to sarge
// When choosing a new action, it depends on the number of nodes owned by my team plus
// whether my team is winning the game.
// Depending on these plus random calls we select one of above actions or one of the
// following:
// 4. send sarge and group1 to nearest non-owned node to sarge,
//    send group 2,4,6 to closest owned node to sarge,
//    send group 3,5,7 to second closest non-owned node to sarge
// 5. send sarge and group1 to nearest non-owned node to sarge,
//    send group 2,4,6 to closest owned node to sarge,
//    send group 3,5,7 to second closest owned node to sarge
// 6. send sarge and group1 to nearest owned node to sarge,
//    send group 2,4,6 to second closest owned node to sarge,
//    send group 3,5,7 to third closest owned node to sarge
// 7. send sarge and group 1, 3, 5, 7 to nearest owned node to sarge,
//    send group 2,4,6 to second closest owned node to sarge,
//
// The rules for selecting amoung these actions are:
// if we own no nodes then
//    randomly pick from 1, 2, 3
// else if we own one node only then
//    randomly pick from 4, 1, 2, 3
// else if we own two nodes and are winning then
//    randomly pick from 5, 4, 7
// else if we own two nodes and are not winning then
//    randomly pick from 1, 2, 3, 4, 5
// else if we own three nodes or more and are winning
//    pick action 6
// else if we own three nodes or more and are not winning
//    pick option 5
