## Shortest distance between points / trave...

Maple

I've got a problem where I need to find the shortest route between a list of points. Each point must only be visited once.

To solve the problem I admit that I have used ChatGPT. While the answer was very helpful, the thing is that it apparently doesn't work (yet). The problem is that the function in the package is not existing.

Here's the ChatGPT code.

Any help appreciated.

## Number of elements returned in SearchTex...

What's the correct command to return the number of elements in this command? It returns an expression sequence, but I didn't manage to get anything useful in return.

StringTools:-SearchAll("aba", "abababababababababab")

## Split table (in worksheet/document)...

Maple

Is it possible to split a table (not the datatype, but the insert - table one)?

## Tabula rasa (table redefined)...

Maple

Something happens when I redefine an indexed value of a table, but I'm not sure what.

Here's the situation before the definition.

eval(WhateverYouNeed["calculations"]["structure"]["connection"]);

TABLE(["Cutright1" = "false", "graindirection1" = 90 Unit(arcdeg), "Cutleft2" = "false",  "lengthleft2" = 500 Unit(mm), "Cutrightsteel" = "false", "lengthleftsteel" = "false", "lengthleft1" = 350 Unit(mm), "lengthright2" = 500 Unit(mm), "connection_1" = "Timber", "lengthrightsteel" = "false", "connection_2" = "Timber", "Cutleft1" = "false", "Cutleftsteel" = "false", "graindirection2" = 0, "graindirectionsteel" = "false", "Cutright2" = "false", "lengthright1" = 150 Unit(mm), "connection_InsideLayers" = 1])

I then try to redefine one specific entry of the table.
WhateverYouNeed["calculations"]["structure"]["connection"]["connection_1"] := GetProperty("ComboBox_connection_1", 'value');

WhateverYouNeed["calculations"]["structure"]["connection"]["connection_1"] := "Timber"

Which gives this new result.

eval(WhateverYouNeed["calculations"]["structure"]["connection"]);

TABLE(["connection_1" = "Timber"])

The rest of the indices and entries of the "connection" table is gone.

## Path and filename length...

Maple

Are there any restrictions regarding path and filename length in Maple?

I am experiencing problems working with a file on a server, path and file length is 207 characters.
