In SAT solving by conflict-driven clause learning, each time a solver detects that a candidate set of variable assignments leads to a conflict, it must look at the causes of the conflict, derive a clause from this (i.e. a lemma in terms of the overall problem) and add it to the set of known clauses. This entails choosing a cut in the implication graph, from which to derive the lemma.

A common way to do this is to pick the first unique implication point.

Per https://users.aalto.fi/~tjunttil/2020-DP-AUT/notes-sat/cdcl.html

A vertex l in the implication graph is a unique implication point (UIP) if all the paths from the latest decision literal vertex to the conflict vertex go through l.

The first UIP by the standard terminology is the first one encountered when backtracking from the conflict.

In alternative terminology, a UIP is a dominator on the implication graph, relative to the latest decision point and the conflict. As such, it could be found by building the implication graph and using a standard algorithm for finding dominators.

But finding dominators can take a nontrivial amount of CPU time, and I get the impression practical CDCL solvers use a faster algorithm specific to this context. However, I have not been able to find anything more specific than 'take the first UIP'.

What is the best known algorithm for finding the first UIP?

1. I am able to successfully run sample code (../examples/6tisch/simple-node) where rpl-lite is implemented and after every 60 seconds root of the network print its routing table. As it uses rpl-lite, only root node stores a routing table.
2. I am looking for a sample code for implementing (storing mode) in this program and print the routing table of each node every 60 seconds.

I have added "MAKE_ROUTING = MAKE_ROUTING_RPL_CLASSIC" in the Make File to enable RPL-Classic

This is an automated SQL backup routine...

This process is supposed to list SQL server names (based on query to a database)... you choose one in the 1st box...

then based on that choice it shows only the databases on that SQL server in the 2nd box...

There are a few TEXT boxes, which are working as desired.

then it passes those values down to the bottom of the code where the backup routine is, executes the routine, and sends an email.

I choose a server from the first drop down, click the button to 'set' that choice as a variable, and a query to a database uses the value from the 1st box to show only the databases on that server...and the correct list of databases is populated into the second drop down.

My problem is I cannot figure out how to properly add a 2nd button to set the choice in that second drop down box as a variable to be used later in the backup routine. So, no value is passed to the $DBName variable at the bottom of the code, so it doesnt know what database to back uip, so FAIL.

Any suggestions would be appreciated.

Using google analytics and it's measurement protocol, I am trying to track eCommerce transactions based on my customers (who aren't end-consumers meaning not sparse unique userid's, locations, etc...) which have a semantic idea of a "sale" with revenue.

The problem is that not all of my logged requests to the ga mp API are resulting in "rows" of transactions when looking at conversions->ecommerce->transactions. And additionally, the revenue reported is respectively missing too. An example of the discrepancy is listing all my non-zero transaction revenue API calls, I should see 321 transactions in the analytics dashboard. However, I see only 106... 30%!!! This is about the same every day even tweaking some attributes which I would think would force uniqueness of a session or transaction.

A semantic difference is that a unique consumer (cid or uid) can send a "t=transaction" with a unique "ti" (transaction id) which overlap and are not serial. I say this to suggest that maybe there is some session related deduplication happening even though my "ti" attribute is definitely unique across my notion of a "transaction". In other words, a particular cid/uid maybe have many different ti's in the same minute.

I have no google analytics javascript or client-side components in use and are simply not applicable to how I need to use google analytics which takes me to using the measurement protocol.

Using the hit-builder, /debug/collect, and logging of any http non-200 responses, I see absolutely no indication that all of my "t=transaction" messages would not be received and processed. Some of the typical debugging points I think are eliminated with this list of what I have tried

• sent message via /collect
• sent multiple message via /batch (t=transaction and t=item)
• sent my UUID of my consumer as cid=, uid= and both
• tried with and without "sc=start" to ensure there was no session deduplication of a transaction
• tried with and without ua (user-agent) and uip (ip override) since it's server side but hits from consumers do come from different originations sometimes
• took into consideration my timezone (UTC-8) and how my server logs these requests (UTC)
• waited 24 to 48 hours to ensure data
• ecommerce is turned on for my view
• amount of calls to measurement protocol are < 10000 per day so I don't think I am hitting any limits

I have t=event messages too although I am taking a step back from using them for now until I can see that data is represented at least to 90%+.

Here is an example t=transaction call.

I use (PostgreSQL) 11.8 and I try to provide full text search opportunity by some columns. For that I created GIN index with multiple fields and coalesce. And after my data base grewto 344747 rows in table products I faced with slow execution in my query. When I execute query example I faced with approximately 4.6s. In analyzing information I see my index used, but still slowly. Bitmap Index Scan on npdbcs_swedish_custom_index present. If I correct made conclusion many time spent to grouping. Do someone know any approach or suggestion how to optimize this query, because I can't imagine how it will work when my db grows to 10 million productsю And most hope data from ANALYZE - Planning Time: 0.790 ms it' possible?

Hello fellow stackoverflowers,

For university I have to create a simple TCP/IP stack for a microcontroller.

I have an unsigned char Buffer of the packets that includes the Headers + the data (if present).

I created a struct for the packets that contains a struct for the ethernet header, a struct for the IPv4 Header, a struct for the ARP header and a 2024 Byte buffer for the actual data.

I would like to assign byte 0 dow to 21 to the Ethernet struct. And 22 down to 53 to the IPv4 Header.

My question now is how do you use memcpy to copy specific intervals from the buffer?

For example if I want to copy buf[21 down to 53] to newbuf[32].

EDIT: So to clarify the question and what I am Actually trying to accomplish:

I send this packet from the PC via Ethernet Cable to a microcontroller. On the microcontroller I want to create a struct that contains all the information that you can see in the picture.

My approach so far is:

This question might seem very stupid, but I'm unable to prove that the only natural number less than 1 is 0. I'm using mathcomp's finType library, and the goal that I want to prove is:
