One Click to the Shortest Walking Route — Automatic Point Reordering

Planning the perfect walking tour involves a delicate balance of captivating stories, historical insights, and, crucially, a logical flow that enhances the user experience. Over time, as you enrich your ARTOUR guides with new points of interest, the walking order can sometimes become a bit… meandering. What started as a clear path can evolve into a zigzagging journey, potentially adding unnecessary distance and confusion for your visitors.

Introducing "Optimize Walking Order": Your New Magic Wand

We're thrilled to announce a significant enhancement to the ARTOUR guide editor: the new "Optimize walking order" feature. Located conveniently within the "Edit route points order" dialog, you'll now find a subtle yet powerful magic-wand button. A single click on this button instantly re-sorts all the stops in your guide into the shortest possible open walking path – because a guide is meant to be walked one way, not necessarily returning to its origin. This ensures your visitors experience a smooth, efficient, and enjoyable journey, maximizing their time exploring rather than navigating inefficient detours.

The impact is immediate and transparent. After optimization, the system will report the concrete distance saving directly to you. For example, you might see a message like: "Walking distance 4.31 km -> 2.87 km (-33%). Review the order, then press Save changes." If your guide's order is already optimal, it will inform you of that too, letting you know your visitors are already on the most efficient path. This clear feedback empowers you to understand the tangible improvements made to your guide.

Crucially, this feature is designed with your control in mind. The proposed, optimized order appears in your drag-and-drop list, but nothing is saved automatically. You retain full flexibility to review the new sequence, make any manual adjustments you deem necessary, and only when you're completely satisfied will pressing "Save changes" commit the new order to your guide. This blend of automation and manual control puts you firmly in the driver's seat.

Under the Hood: Precision, Not Prediction

For the technically curious among our creators, let's peek behind the curtain. When we set out to solve the challenge of optimizing walking routes, we knew we needed a solution that was robust, reliable, and perfectly suited to the task. This isn't a job for a general-purpose AI model sorting coordinates; it's a classic computational problem known as the Traveling Salesman Path (TSP) problem.

Instead of relying on probabilistic AI, our feature employs a sophisticated geometric algorithm executed right in your browser. It calculates real walking distances between the geographical coordinates of your points. It then uses a "nearest-neighbor" approach, trying every possible starting point to find the best initial path, followed by a "2-opt refinement" process to further improve the route by swapping segments until no better path can be found. The result? A highly efficient, optimized route that arrives instantly, costs nothing to run, and is completely deterministic – the same set of points will always yield the same optimal path. Furthermore, it comes with the exact distance saved, a guarantee that would be difficult to achieve with less precise methods.

It’s a prime example of using the right tool for the job: a well-understood, efficient algorithm delivering a precise, measurable outcome for a specific problem.

Practical Safety & Prerequisites

We've also built in some practical safeguards. Points with missing or broken geographical coordinates (latitude/longitude) won't derail your optimization. Instead, they are intelligently "parked" at the end of the list with a clear warning, ensuring they don't drag your route off the map. To perform an effective optimization, the feature requires at least three located points in your guide to calculate a meaningful path.

This new feature is designed to save you valuable time, reduce manual effort, and ultimately provide an even better, more streamlined experience for your guide users, ensuring every step they take is part of a thoughtfully planned, efficient journey. We believe this blend of smart technology and user control will become an indispensable tool for all ARTOUR content creators.
