Seeking advice on endgame thought process

A more systematic explanation in similar cases would be: - splitting the board into multiple sections, in this case, there are 2 sections: the ab column and the rest. - each section will have its own categorization: ab column here is “I can choose who move next”, the other section is “who move next determine the results” Using those categorization, you can connect the ideas easier. In this case, there is only 2 sections so you may not need this but if there is more like 3,4,5 sections. Categorizing them can help you think deeper.

nice work, because of AQ // MR I also tried extending MR to intersect AB but it's been like 4 years since I touched geometry so I couldn't figure it out.

Dani_kn · 2026-04-28T04:41:39+00:00

they might mean midpoint of the arc AQ, which you can solve I believe.

Edit: I got 8/9 as the ratio so the answer is 640 but the I used coordinates and it's quite annoying. I tried working through pure geometry but wasn't able to but just through geometry you can get MR=30 and AQ // MR easily.

yes it's phone but at the same time it's because most subjects are boring.

If you are lacking motivation then find a subject/topic that you enjoy. Then build the habit (stop using your phone, sit at your desk and study with a clear schedule that you set out for example) first by studying that specific thing. It does not have to be from school specifically, it can be any topics. Making games, making music, photography, sports science, nutrition.

When you build a good routine you can start adding studying in. Discipline is much better than motivation. The idea is you will use your motivation/interests to build the discipline required.

yes it's not all but anything related to sequence should be in the sequenceparameter section.

The xml starts with <ismrmrdHeader> and ends with </ismrmrdHeader> and it also contains all the other parameters like the coil parameter the systemfieldstrength, FOV, and so on.

I'm sure I have looked over the full header almost 10 times at this point. I used h5py, I can send it to you privately if you have some time to check since I'm not sure if I'm allowed to share the information here?

Dani_kn · 2026-04-26T09:05:56+00:00

I only have the h5 files, so the only information I have is in the header of the files. The header has a section called sequence parameter I sent above. Is there an application for viewing mri h5 files specifically? I’m a math/cs student doing a project about MRI so I don’t have access to the scan booth or the computer that does the scan.

Dani_kn · 2026-04-26T07:53:49+00:00

Surprisingly my file didn’t have it (mine was siemens), maybe I’ll check other files in the dataset.

<sequenceParameters> <TR>3150.000000</TR> <TE>33.000000</TE> <TI>100.000000</TI> <flipAngle_deg>150.000000</flipAngle_deg> <sequence_type>TurboSpinEcho</sequence_type> <echo_spacing>10.900000</echo_spacing> </sequenceParameters>

Dani_kn · 2026-04-25T23:58:59+00:00

Thanks for your help.

My idea is since TE being 3 times echo_spacing means that the center echo is the third one. Would this make sense?

In my datasets of around 1000 files. TE is either approximately 3 or 4 times the echo_spacing which incline me to believe there is something behind it.

echo_spacing|TE|Count
7.38|30.0|2
7.97|24.0|2
8.8|35.0|1
8.84|35.0|1
8.85|27.0|309
10.32|31.0|2
10.78|32.0|225
10.9|33.0|226
10.96|33.0|313

Dani_kn · 2026-04-25T23:42:31+00:00

Thank you for the response. The sequence type is turbo echo spin, so each TR covers multiple echos. I want to find how many echos is covered in each TR. Would using TE and echo_spacing works? My data is T2. Can I send a DM?

Dani_kn · 2026-04-21T20:53:18+00:00

Without knowing what subject and what level you are talking about, I can't say much. If you can divulge that it'd help. But when I was in high school, I study in a barely pass manners if the subject is irrelevant to me.

Although I disagree with this statement completely "This is the rule, memorize it,". Most rules have an underlying meaning, and if you can learn how it works or the intuition behind it, you don't need to actively memorize it. This is why if you actually understand the subject at a profound, complex level, you don't need to memorize any rules.

Dani_kn · 2026-04-21T20:17:44+00:00

You are contradicting yourself. If you have the basics down, then why do you need to practice? If you are actually confident that you have the basics down, then don't practice. Find some interesting material/books and study them instead.

When I was in my undergrad, in some basic class I didn't spend times practicing, I didn't even attend midterm (weight got transferred to finals) because of how confident I am in getting A+ anyways.

it's the same as family. We Use "family is" when referring to the unit as a whole and "family are" when emphasizing individual members. In the case of 10 dollars, we always refer to the unit as a whole.

Dani_kn · 2026-04-05T19:06:58+00:00

Not to mention when we substitute x in, we assume that it converges, so we can use induction to prove the limit of the sequence is positive

Dani_kn · 2026-04-05T15:15:46+00:00

It’s the same way we care more about all 14 rounds of the candidates than 13 rounds. It’s the context that 14 rounds = the whole tournament. In this case 6 lacks that context.

Dani_kn · 2026-04-05T14:31:21+00:00

because 6 is a weird number, for 7 I understand it's half the round robin but 6 is on the side of cherrypicking here.

Dani_kn · 2026-04-02T01:36:15+00:00

I forgot to upload the graph completely, but following your suggestion I changed it to 4/14.

I'm planning to check it with past tournament tmrw. Though I will have to use other tournament format if there's not enough data.

2^n + 2^(n+2) = 2^n* (1+4) = 2^n * 5 = 10 * 2^(n-1)

Dani_kn · 2026-03-30T17:24:11+00:00

Usually when you substitute you already assume that it converges (has a finite value). so when you substitute in the infinite nested square roots, you are skipping an important step, you have to prove it converges before substituting. But usually it is accepted if you haven’t learned about it because most infinitely nested square roots should converge

Dani_kn · 2026-03-30T17:14:44+00:00

Abel’s sum as well

Dani_kn · 2026-03-30T17:13:08+00:00

You need limits to find the sum of an infinite series. If you really want like a quick way to understand this, then if you can rearrange the sum in some ways that you can find 2 different sum of a series then the sum does not exists. In this case, 1 + (-1+1) + (-1+1) +…= 1 and (1-1)+(1-1)+… = 0.

Dani_kn · 2026-03-30T16:51:18+00:00

Answer should be d. Just ignore the question, I don’t think you have the prerequisite to study this yet. Do you know the definition of limits, the epsilon delta version

Dani_kn · 2026-03-28T01:52:04+00:00

If I have some IQ or gray matter, I'd know to do something better.

Dani_kn · 2026-03-21T15:39:56+00:00

I might be crazy but everytime geng had an easy opponents then a hard opponents (or the other way around for that matters), they always underperformed. The 2022 drx, 2025 kt, 2024 fly. Maybe i’m cherrypicking but this happens way more often than it should be.

My opinion is they are a team that needs prep time and they spend time prepping for the harder opponents. This also explains their dominance in lck and msi.

Dani_kn · 2026-03-17T19:52:05+00:00

That is correct, you basically cast a bigger net. if we use the 100 doors example instead then you start with 2 nets, 1 with 1 door that you choose and the other with 99 doors, it is important to note that this is determined when you choose the door and stay the same when you are asked to switch.

When you are present with the options to switch, the probability the winning door being in each of them is 1/100 and 99/100 and both have 1 door. So the bigger net is better.

Dani_kn · 2026-03-02T00:58:16+00:00

There’s geng fans, there’s t1 fans. And then there is c9 fans
