* TODO:
|
|
* The current solution is not optimal, as it's preferable to buy new nodes, even if upgrading is cheaper.
|
|
* TODO:
|
|
* It may be helpful to calculate the money per second of each node on average, (total mps / total nodes) and compare
|
|
* it to the time it would take to purchase the next cheapest upgrade, and if the average mps is greater than the
|
|
* negative mps of the upgrade cost, then buy a new node.
|
|
* TODO:
|
|
* Potential Ideas:
|
|
* Find a way to calculate how much mps an individual upgrade would give, and compare it to the average mps of the node.
|
|
* ns.hacknet.getNodeStats(0).production
|
|
* If the upgrade mps is greater than the average mps, then buy the upgrade.
|
|
* If the upgrade mps is less than the average mps, then buy a new node.
