Improvements to AI valuation of their own draft picks in trades

January 9, 2023-

There have been a lot of blog posts about the trade AI in the past - just click that Trades tag above if you don't believe me! And yet, the trade AI remains flawed.

The most ambitious (and so far failed) attempt at improving the trade AI came from nicidob, where he tried to come up with a model to predict how the various "assets" a team owns (not just players and picks, but also cap space) contribute to the likelihood of winning a championship over the next several years.

Bug fix for trading picks during the draft

August 18, 2022-

This isn't that important of a bug fix, and I bet most people won't notice either way. But it does need a bit of explanation to make sense, so here is a blog post!

Trade finding algorithm improvements

May 3, 2021-

This is about the trade finding algorithm, not the trade AI itself. There are no changes to which trades will be accepted or rejected. But there are some changes to the algorithm powering the trading block, AI-AI trades, and the "What would make this deal work?" button.

The end result of these changes is that the AI is more upfront and consistent. It gives you its best proposal right away, rather than trying to be cute and maybe sometimes not tell you right away. And when you spam that "What would make this deal work?" button, it will keep giving you the same answer unless something has changed.

I think it feels a lot more reasonable this way, and I hope you agree. Read on for all the details.

Trade frivolities: biggest trades and most lopsided trades

Following up to the recent updates that added a lot of detail to historical trades, today I added two new frivolities, in a brand new Trades section:

Biggest Trades: Trades involving the best players and prospects.

Most Lopsided Trades: Trades where one team's assets produced a lot more value than the other.

You can find them within a league at Tools > Frivolities.

Improved trade details and a new Trade Summary page

When you make a trade in Basketball GM or Football GM, a summary of that trade is logged and shows up in the transactions list and the news feed. A mildly annoying thing about that is how it handles draft picks. Sure it'll say the trade included a 2021 2nd round pick, but if you check back after the 2021 draft, there's no new information. It doesn't say which player was selected with the pick, which makes it difficult to evaluate trades.

I've gotten many requests to do something about that, and I'm happy to announce that I have finally done something!

Why AI teams are reluctant to trade away draft picks

May 16, 2014-

As has been noticed, it can be quite difficult to convince an AI team to part with draft picks, even if they are a "contending" team. It takes a little more than a Tweet to explain, though.

New Improved Trade AI

February 15, 2014-

The trade AI in Basketball GM has never been that bad, but people still found ways to exploit it. As I fixed those exploits, the code grew and grew and grew to the point where it was too confusing to manage.

So I ripped it all out and started over. Now, there is a new and (hopefully) improved trade AI. It was always decent at valuing current player production (that's easy, just look at the stats), but my main goal here was to improve how it valued other things. Like draft picks, overvalued/undervalued contracts, injured players, etc.
