Is this a valid heuristic for Dots and Boxes to reduce the branching factor of the search tree?

I am implementing an AI based on the MiniMax algorithm that plays the game Dots and Boxes. I would like to reduce the branching factor of the search tree, by introducing a heuristic rule that limits the number of successor states. However, I am not sure whether there exist any situations, where this rule would exclude the optimal move and make the AI play worse.

In the game 2 players take turns, until one of them captures a box, after which they have to make another move, possibly capturing another box etc. For this purpose, I define successor states of $ S$ to be all states, where the opponent gets the move, or the terminal state. If a player made a capture and still has to make another move, then the current state is not yet a successor state of $ S$ – the player has to continue making moves until they’re unable to.

My rule is as follows:
Assume a player makes a series of captures from a starting state $ S$ and ends it with a move $ m$ , after which the turn goes to the opponent. Then it’s always better or at least not worse for the player to have made as many captures as possible before finishing the sequence with $ m$ .

This means that any state $ S$ always has less successors, then there are legal moves. All successors where the player captures $ n$ boxes and finishes with move $ m$ are discarded, unless $ n$ is the maximum number of boxes that can be captured such that $ m$ can still be a finishing move. For example, in the following state:
example state
immediately capturing the 4 boxes leads to a loss, while dividing them into 2 small chains, 2 boxes each, with the move (2,2)-(2,3) leads to a victory. The optimal strategy is consistent with the rule, as it would not be possible to finish with the move (2,2)-(2,3), if any of the boxes were captured. The rule excludes all successors, where the player captures 1 or 2 boxes, from being considered.

How can i write script for search two different List columns of search boxes related data show on grid view in SPFX?

Am able to search the PR_Number column data, the same i want to search for Description as input in another search box and show the gridview in SPFx.

Alternatives to boxes

I have a box problem. 90% of all my original magic items either are boxes, or are inside boxes. I try to hide it by making them interesting shapes, but ultimately a box is a box.

It has gotten to the point where if I even so much as mention a box, the words “a box, must be important!” can be heard around the table.

How do I break my box habit, and what alternatives do I have to boxes?

nested boxes algorithm

I am given a set of 3D boxes {$ B_1$ , $ B_2$ $ B_n$ } and each box have length, width and height. But these values are interchangeable since I can rotate the box. I need to find out the maximum sequence of nested boxes.

I have tried this problem using sort. But I still get stuck. I used built in sort function to sort all boxes by length in ascending order. I read the reference about this question and learned that people used radix sort. I have know idea how radix sort is applied here because all sorts I am familiar is comparison sort.

Add boxes for generic_fields

Some fields could be added by default, but not required. Its not a perfect solution, it would me much better to create additional .dat file, where we could define custom types (just like in engine.ini) that can be used for generic fields <- all of them could pop – up in project settings as additional but not required. But they should not be overriden by default Engines data fields ? Its a thing to discuss.

Check off the boxes you wish to unsubscribe from

In attempting to unsubscribe from a company’s emailing list, I was directed to a website with the following form.

enter image description here

Note the phrase “Check off the boxes… you wish to unsubscribe from.” Is this some type of standard phrasing? The use of the terms off and unsubscribe seem to make the sentence ambiguous; should I check or uncheck? (The default page has all check boxes unchecked.)

Is there a way this company can improve their phrasing?

Is there a recommended size for search boxes?

Do users change their search patterns if the search is shorter? Do users search less if the search box is too large?

The only article I’d found is a 2009 Smashing Magazine article:

The [Nielsen] study found that the average search box is 18-characters wide. The data showed that 27% of queries were too long to fit into it. Extending the box to 27 characters would accommodate 90% of queries. Remember, you can set widths using ems, not just pixels and points. One em is the width and height of one “m” character (using whatever font size a website is set to). So, use this measure to scale the width of the text input field to 27-characters wide.

In general, search boxes are better too wide than too short, so that users can quickly review, verify and submit the query. This guideline is very simple but unfortunately too often dismissed or ignored. Some padding in the input field can also improve the design and user experience.

Should alert boxes be avoided at any cost?

Thanks to Gabriel Svennerberg and Sam K for this one – raised in a comment here.

I was fairly casual about alert boxes until a run of user tests where an alert box was put up to warn learners that if they left an online course at a particular point they would lose work they’d already done. Leaving aside the fact that that situation should probably never arise in the first place (! no poka-yoke there), we were very alarmed by what we saw.

Users basically clicked on that alert box in a completely random way, based on their prior experience of alert boxes in other software.

Only a smallish minority of users read the text of the alert box. Most just clicked something: either the button that kept them safely on the page, or the one that deleted their work, or the ‘X’ to close the dialogue. Most were bemused by whatever came next. Digging deeper, it seemed that many people just had a set action for ‘error’ boxes – click something to make it go away.

On that basis, how far do we go to avoid alert boxes?
