The goal of my algorithm is to find the optimal melding for a particular set of cards, which is one that minimizes the sum of the values of all the deadwood (The values of number cards are their associated numbers, the value of the ace is 1, and the value of face cards is 10.).

The second is that when things don’t work – in other words, the kind of learning you are looking for is just not happening – there are between 2 and 2.8 zillion parameters that can be adjusted to change how the Neural Network works, how the learning works, or both. How to interpret a large Cohen's d when p-value is non-significant and CI's are close to 0.

At that point grand total for each player is calculated, with bonuses, and the player with the highest score wins the whole game.

Here are potentially useful resources for learning from Jack of Hearts). Under this assumption, the algorithm could just calculate the sum of the values of the run and the sum of the values of all the sets, and keep whichever was greater. You can rearrange the tiles on the board to fit your needs. Ed has been delivering software systems for an undisclosed number of years. For the rules, see below.
