What I'll do next is to give you another programming assignment.

次は別のプログラミングの問題を出します

Rather than printing out the particles themselves,

粒子ではなく

I want you to print out the overall quality of the solution

解の全体的な品質を出力してください

and to do this, I've programmed for you an "eval" code which takes in as a robot position and a particle set,

ロボットの位置と粒子の集合を引数とするコードevalをプログラミングしました

and it computes the average error of each particle, relative to the robot pos

方向ではなくxとyのロボットの位置に対して

in "x" and "y"--not in the orientation.

各粒子の平均的な残差を計算します

And the way it does it, it basically compares the "x" of the particle with the "x" of the robot,

粒子のxとロボットのxを比較し

computes the Euclidian distance of these differences, and averages all of those.

その差についてユークリッド距離を計算してすべての値の平均を出します

So it sums them all up

つまりすべてを合計するのです

and it averages them, through the number of particles over here, which is upper caps N.

粒子の数で平均して上限がｍとなります

Now, there's some funny stuff over here.

面白いものがいくつかできました

The reason is, the world is cyclic

この世界はサイクリックなので

and it might be that the robot is at 0.0 or at 99.9.

ロボットは0．0 または99．9の位置にいるかもしれません

It's about the same values but, according to this calculation over here, they'd be different.

ほぼ同じ値ですがこの計算によれば異なる値です

So while there's normalization over here,

ここに正規化がありますが

I make sure that the cyclicity of the world

この世界がサイクリックであることが

doesn't really affect negatively the estimated error I've enclosed in the boundary. You might parse this.

境界線で囲った推定される誤差に悪影響を及ぼさないことを確かめます

I'm adding "world_size" over to the computer model operation and then

コンピュータモデルの演算にworld＿sizeを加えて

subtract the same thing over here--I can't even see it. It's just too long a line.

同じものを引きますが行が長すぎて見えません

Be that as it is, I want you to take the function, "eval",

いずれにせよeval関数を用いて

and produce a sequence of performance evaluations.

一連の性能評価をしてみてください

And if we hit the run button, I want you to produce something like this stuff over here:

Runボタンを押したら次のような結果が出るようにしてください

4.9, 3.6, 2.9, 2.8, 3.1.

4．9、3．6、2．9、2．8、3．1です

This is the residual error.

これが残差です

Remember, it's a world of size 100 by 100,

世界のサイズは100×100なので

so this is actually a relatively small error, compared to the world's size.

実際には世界の大きさに比べると小さい残差です

Can you code it so I get, for each iteration,

反復ごとに

the error number produced by this routine over here?

このルーチンによって生成される残差が得られるようにコーディングできますか？
