In this page, I will show the algorithms I chose for the 4 cases of the Pattern 4.
I call this pattern “meter”.
No. 17: UFR and UBR look at a side

Algorithm: y’ R’ U R2 D r’ U’ r D’ R’

No. 19: UFR looks at a side
https://www.speedcubedb.com/a/3×3/VLSNE/VLS_19
Algorithm: U F’ L’ U2 L F R U2′ R’

No. 16: UBL looks at a side
https://www.speedcubedb.com/a/3×3/VLSNE/VLS_16
Algorithm: F’ U2′ F U’ R’ F R2 U R’ U’ F’

No. 18: None of the CP looks at a side
https://www.speedcubedb.com/a/3×3/VLSNE/VLS_18
Algorithm: R2 U’ D r’ U r D’ R’ d’ r U’ r’

In this pattern, the UBL can not be used as the switch. But the good thing is that you only need to look at the R face to know the case.
