QUESTION
I am modeling a Time-constrained CVRP. The problem is to minimize the total travel time (not including the package dropping time) subject to vehicle (delivery) capacity and total time spent (per vehicle) constraints. The package dropping time refers to an additional time to be spent at each node, and the total time spent equals to the travel time plus this additional time. I have the below model that works for a single vehicle-type case. I would like to introduce two-vehicle type concept in there, meaning that I have a set of V1
type vehicles and another set of V2
type vehicles. The only difference of the vehicle-types is the per time cost of travel. Let x
denote the per time unit cost of travel by V1
, and y
denote the per time unit travel cost of V2
. How can I design the model so that it incorporates this additional aspect?
ANSWER
Answered 2021-Jun-13 at 13:34Simply register two transits callbacks (i.e. one per vehicle type)
Then use the overload of AddDimension() to pass an array of registered transit callback index.

I'm trying to make a small simulation of traveling salesman in Unity C# and I can't get through this, my code looks right but start and nxtCity vectors always result in the same position, I really can't understand why, could any of you help?
cities is the number of total cities
positions is the array of cities taken from cities generator these two values are right in unity editor
Here the code:

Answered 2021-Jun-11 at 00:22Unity's Random.Range with (int, int) overload (NOT float, float) generates random number in range [min; max), max is exclusive, so if you call var randomInt = Random.Range(0, 1)
result will be always 0. var randomInt = Random.Range(0, 2)
would be 0 or 1, e.t.c
QUESTION
I'm building a web app using Laravel 8 and one thing I tend to struggle with is the complex relationships and accessing the data. I've started reading on hasManyThrough
relationships but I'm not convinced that's the correct way to do it for my scenario.
The app is used by travelling salesmen to check in to a location when they arrive safely.
I have three main tables:
Locations
(where they are visiting),Checkins
(where their check in data is stored, e.g. time),Users
This is where it gets a little complex and where I find myself not being able to see the wood for the trees...
- Locations have many users, users have many locations. Many-to-many pivot table created.
- Locations have many check ins, check ins have many locations. Many-to-many pivot table created.
- Check ins have many users, users have many check ins. Many-to-many pivot table created.
As such they're all created using a belongsToMany
relationship.
Now what I'd like to do is access the user
of the check in
so I can call something similar to on my show.blade.php
:
ANSWER
Answered 2021-Jun-14 at 23:46You said "Check ins have many users", you seem to want the singular user for a check-in, but currently that would result in many users. It sounds like users check-in in a many to one relationship
Also $checkin->created_at
will be by default a carbon object, so you can just go $checkin->created_at->format('jS F Y')
Also don't mix using compact
and with
, stay consistent and use only 1 as they achieve the same thing
Also $checkin->users()->name
won't work, if you use the brackets on syntax is only returns a query builder instance, which you would need to call get on like $checkin->users()->get()
, or you could use $checkin->users
which will fetch them anyway. You may want to look into using with('relation')
on query builder instances to stop N+1 queries if you want to dive a little deeper. Lastly $checkin->users()->get()->name
also won't work as your user relation is many to many which returns a collection, which again points to you should have a belongsTo relationship called user
without a pivot table
QUESTION
my question is a little complicated, I am building a trip-related web application where users can book trips. So I have made a function that increases the number of travelers as the user clicks the + sign. when this function is called it changes the state and another function gets triggered that displays the form to fill in the traveler details. Now this form is rendered according to the number of travelers traveling. how can I set that data in an array of objects?
here's a screenshot guide:
I want the data to be in the state like this:

QUESTION
I am new to zimpl and I am currently trying to modell the GTSP. The setting is that we have nodes which are grouped into clusters. My problem is i dont know how to implement in zimpl which node belongs to which cluster.
What I did so far:
set V:= {1..6};
set A:= { in V*V with i < j};
set C:= {1,2,3};
set W:= { in C*C with p < q};
set P[]:= powerset(C);
set K:= indexset(P);
I am guessing something is missing because i want to group node 1,2
in cluster 1
, 3,4
in cluster 2
and 5,6
in cluster 3
.
Some background Information:
Let G = (V, A)
be a graph where V=1,2,...,n
is the set of nodes and A = {(i, j): i, j ∈ V, i ≠ j}
is the set of directed arcs (or edges), and let c_ij
be the travel distance (or cost or time) from node i to node j. Let V1, V2, ... , Vk
be disjoint subsets of V such that union of these subsets equals to V. These subsets are called clusters. The GTSP is to find the tour that (i) starts from a node and visits exactly one node from each
cluster and turns back to the starting node (ii) never
visit a node more than once and (iii) has the minimum total tour length.
Associated with each arc, let x_ij
be a binary variable equal to “1” if the traveler goes from node i to node j, and “0” otherwise.
Thats the mathematicl model I want to model:
min∑i∈V ∑j∈V\{i} cijxij
subject to:
∑i∈Vp ∑j∈V\Vp xij = 1 (p= 1, ..., k)
∑i∈V\Vp ∑j∈Vp xij = 1 (p= 1, ..., k)
∑j∈V\{i} xji − ∑j∈V\{i} xij = 0 (∀i∈V)
xij∈{0,1} ∀(i, j)A
up−uq+k ∑i∈Vp ∑j∈Vq xij+(k−2)∑i∈Vq ∑j∈Vp xij ≤ k−1 (p≠q;p,q=2,...,k)
up≥0 (p=2, ..., k)
(Thats the link for the paper: http://www.wseas.us/e-library/conferences/2012/Vouliagmeni/MMAS/MMAS-09.pdf)
Maybe someone can help! thanks
...ANSWER
Answered 2021-Jun-12 at 15:36You can use an indexed set (just as u did to implement the powerset of C
) and assign the sets as needed. Try this for example:

I have a program that summarizes non-normalized data in one table and moves it to another and we frequently get a duplicate key violation on the insert due to bad data. I want to create a report for the users to help them identify the cause of the error.
For example, consider the following contrived simple SQL which summarizes data in the table Companies and inserts it into CompanySum, which has a primary key of State/Zone. In order for the INSERT not to fail, there cannot be more than one distinct combinations of Company/Code for every unique primary key State/Zone combination. If there is, we want the insert to fail so that the data can be corrected.

Answered 2021-Jun-12 at 07:10With MapStruct you can define mapping between different iterable. However, you can map from a nested listed into a top level list in a method (You can if it is wrapped though).

I've seen a lot of examples of easing with Vector2.Lerp

But I want to use Vector2.MoveTowards
because I am randomizing the distance my NPC is traveling, and I want the speed of the NPC to always be constant regardless of the distance traveled. Ideally, would like to control the easing granularly with an AnimationCurve
if that's possible, but a smooth step function would be ok too. Here is the simplified code that I'm using now (using Behavior Designer so the methods are a bit different):

Answered 2021-Jun-10 at 20:37Okey so there is one first issue: Never use ==
for comparing two float
values!
Even a situation like 5f * 0.2f / 10f == 1f
might fail because due to floating point precision it might actually be 0.9999999
or 1.0000001
.
Instead you usually rather check against a certain range like e.g.
